| CVE-2025-24970 | High | 2025-02-10 | No exploit published | Proof of concept only | Netty, an asynchronous, event-driven network application framework, has a vulnerability starting in version 4.1.91.Final and prior to version 4.1.118.Final. When a special crafted packet is received via SslHandler it doesn't correctly handle validation of such a packet in all cases which can lead to a native crash. Version 4.1.118.Final contains a patch. As workaround its possible to either disable the usage of the native SSLEngine or change the code manually. |
| CVE-2025-23184 | High | 2025-01-21 | No exploit published | No public exploit | A potential denial of service vulnerability is present in versions of Apache CXF before 3.5.10, 3.6.5 and 4.0.6. In some edge cases, the CachedOutputStream instances may not be closed and, if backed by temporary files, may fill up the file system (it applies to servers and clients). |
| CVE-2024-43709 | High | 2025-01-21 | No exploit published | No public exploit | An allocation of resources without limits or throttling in Elasticsearch can lead to an OutOfMemoryError exception resulting in a crash via a specially crafted query using an SQL function. |
| CVE-2024-38819 | High | 2024-12-19 | Protected by Waratek | Working exploit published | Applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn are vulnerable to path traversal attacks. An attacker can craft malicious HTTP requests and obtain any file on the file system that is also accessible to the process in which the Spring application is running. |
| CVE-2024-28168 | High | 2024-10-09 | Protected by Waratek | No public exploit | Improper Restriction of XML External Entity Reference ('XXE') vulnerability in Apache XML Graphics FOP. This issue affects Apache XML Graphics FOP: 2.9. Users are recommended to upgrade to version 2.10, which fixes the issue. |
| CVE-2024-47197 | High | 2024-09-26 | No exploit published | No public exploit | Exposure of Sensitive Information to an Unauthorized Actor, Insecure Storage of Sensitive Information vulnerability in Maven Archetype Plugin. This issue affects Maven Archetype Plugin: from 3.2.1 before 3.3.0. Users are recommended to upgrade to version 3.3.0, which fixes the issue. Archetype integration testing creates a file called ./target/classes/archetype-it/archetype-settings.xml This file contains all the content from the users ~/.m2/settings.xml file, which often contains information they do not want to publish. We expect that on many developer machines, this also contains credentials. When the user runs mvn verify again (without a mvn clean), this file becomes part of the final artifact. If a developer were to publish this into Maven Central or any other remote repository (whether as a release or a snapshot) their credentials would be published without them knowing. |
| CVE-2024-7254 | High | 2024-09-19 | No exploit published | No public exploit | Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups / series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker. |
| CVE-2024-38816 | High | 2024-09-13 | Protected by Waratek | Exploited | Applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn are vulnerable to path traversal attacks. An attacker can craft malicious HTTP requests and obtain any file on the file system that is also accessible to the process in which the Spring application is running. Specifically, an application is vulnerable when both of the following are true: * the web application uses RouterFunctions to serve static resources * resource handling is explicitly configured with a FileSystemResource location However, malicious requests are blocked and rejected when any of the following is true: * the Spring Security HTTP Firewall https://docs.spring.io/spring-security/reference/servlet/exploits/firewall.html is in use * the application runs on Tomcat or Jetty |
| CVE-2024-43044 | High | 2024-08-07 | Protected by Waratek | Proof of concept only | Jenkins 2.470 and earlier, LTS 2.452.3 and earlier allows agent processes to read arbitrary files from the Jenkins controller file system by using the `ClassLoaderProxy#fetchJar` method in the Remoting library. |
| CVE-2024-25638 | High | 2024-07-22 | No exploit published | No public exploit | dnsjava is an implementation of DNS in Java. Records in DNS replies are not checked for their relevance to the query, allowing an attacker to respond with RRs from different zones. This vulnerability is fixed in 3.6.0. |
| CVE-2024-32007 | High | 2024-07-19 | No exploit published | No public exploit | An improper input validation of the p2c parameter in the Apache CXF JOSE code before 4.0.5, 3.6.4 and 3.5.9 allows an attacker to perform a denial of service attack by specifying a large value for this parameter in a token. |
| CVE-2024-36114 | High | 2024-05-29 | No exploit published | No public exploit | Aircompressor is a library with ports of the Snappy, LZO, LZ4, and Zstandard compression algorithms to Java. All decompressor implementations of Aircompressor (LZ4, LZO, Snappy, Zstandard) can crash the JVM for certain input, and in some cases also leak the content of other memory of the Java process (which could contain sensitive information). When decompressing certain data, the decompressors try to access memory outside the bounds of the given byte arrays or byte buffers. Because Aircompressor uses the JDK class `sun.misc.Unsafe` to speed up memory access, no additional bounds checks are performed and this has similar security consequences as out-of-bounds access in C or C++, namely it can lead to non-deterministic behavior or crash the JVM. Users should update to Aircompressor 0.27 or newer where these issues have been fixed. When decompressing data from untrusted users, this can be exploited for a denial-of-service attack by crashing the JVM, or to leak other sensitive information from the Java process. There are no known workarounds for this issue. |
| CVE-2024-30172 | High | 2024-05-14 | No exploit published | No public exploit | An issue was discovered in Bouncy Castle Java Cryptography APIs before 1.78. An Ed25519 verification code infinite loop can occur via a crafted signature and public key. |
| CVE-2024-29857 | High | 2024-05-14 | No exploit published | No public exploit | An issue was discovered in ECCurve.java and ECCurve.cs in Bouncy Castle Java (BC Java) before 1.78, BC Java LTS before 2.73.6, BC-FJA before 1.0.2.5, and BC C# .Net before 2.3.1. Importing an EC certificate with crafted F2m parameters can lead to excessive CPU consumption during the evaluation of the curve parameters. |
| CVE-2023-5685 | High | 2024-03-22 | No exploit published | No public exploit | A flaw was found in XNIO. The XNIO NotifierState that can cause a Stack Overflow Exception when the chain of notifier states becomes problematically large can lead to uncontrolled resource management and a possible denial of service (DoS). |
| CVE-2024-24549 | High | 2024-03-13 | Mitigation candidate | Proof of concept only | Denial of Service due to improper input validation vulnerability for HTTP/2 requests in Apache Tomcat. When processing an HTTP/2 request, if the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1 through 9.0.85, from 8.5.0 through 8.5.98. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M17, 10.1.19, 9.0.86 or 8.5.99 which fix the issue. |
| CVE-2024-25710 | High | 2024-02-19 | No exploit published | No public exploit | Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in Apache Commons Compress.This issue affects Apache Commons Compress: from 1.3 through 1.25.0. Users are recommended to upgrade to version 1.26.0 which fixes the issue. |
| CVE-2023-52428 | High | 2024-02-11 | No exploit published | No public exploit | In Connect2id Nimbus JOSE+JWT before 9.37.2, an attacker can cause a denial of service (resource consumption) via a large JWE p2c header value (aka iteration count) for the PasswordBasedDecrypter (PBKDF2) component. |
| CVE-2023-51441 | High | 2024-01-06 | No exploit published | No public exploit | ** UNSUPPORTED WHEN ASSIGNED ** Improper Input Validation vulnerability in Apache Axis allowed users with access to the admin service to perform possible SSRF This issue affects Apache Axis: through 1.3. As Axis 1 has been EOL we recommend you migrate to a different SOAP engine, such as Apache Axis 2/Java. Alternatively you could use a build of Axis with the patch from https://github.com/apache/axis-axis1-java/commit/685c309febc64aa393b2d64a05f90e7eb9f73e06 applied. The Apache Axis project does not expect to create an Axis 1.x release fixing this problem, though contributors that would like to work towards this are welcome. |
| CVE-2023-46589 | High | 2023-11-28 | No exploit published | No public exploit | Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M11 onwards, 10.1.16 onwards, 9.0.83 onwards or 8.5.96 onwards, which fix the issue. |
| CVE-2023-44487 | High | 2023-10-10 | Mitigation candidate | Exploited | The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. |
| CVE-2023-39410 | High | 2023-09-29 | Protected by Waratek | No public exploit | When deserializing untrusted or corrupted data, it is possible for a reader to consume memory beyond the allowed constraints and thus lead to out of memory on the system. This issue affects Java applications using Apache Avro Java SDK up to and including 1.11.2. Users should update to apache-avro version 1.11.3 which addresses this issue. |
| CVE-2023-1370 | High | 2023-03-22 | No exploit published | Proof of concept only | [Json-smart](https://netplex.github.io/json-smart/) is a performance focused, JSON processor lib. When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively. It was discovered that the code does not have any limit to the nesting of such arrays or objects. Since the parsing of nested arrays and objects is done recursively, nesting too many of them can cause a stack exhaustion (stack overflow) and crash the software. |
| CVE-2021-46877 | High | 2023-03-18 | Protected by Waratek | No public exploit | jackson-databind 2.10.x through 2.12.x before 2.12.6 and 2.13.x before 2.13.1 allows attackers to cause a denial of service (2 GB transient heap usage per read) in uncommon situations involving JsonNode JDK serialization. |
| CVE-2023-26464 | High | 2023-03-10 | Protected by Waratek | Exploited | ** UNSUPPORTED WHEN ASSIGNED ** When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. |
| CVE-2023-24998 | High | 2023-02-20 | No exploit published | No public exploit | Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is not enabled by default and must be explicitly configured. |
| CVE-2022-42252 | High | 2022-11-01 | No exploit published | No public exploit | If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 to 10.1.0 was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x only), Tomcat did not reject a request containing an invalid Content-Length header making a request smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header. |
| CVE-2022-42004 | High | 2022-10-02 | Protected by Waratek | No public exploit | In FasterXML jackson-databind before 2.13.4, resource exhaustion can occur because of a lack of a check in BeanDeserializer._deserializeFromArray to prevent use of deeply nested arrays. An application is vulnerable only with certain customized choices for deserialization. |
| CVE-2022-42003 | High | 2022-10-02 | No exploit published | No public exploit | In FasterXML jackson-databind before versions 2.13.4.1 and 2.12.17.1, resource exhaustion can occur because of a lack of a check in primitive value deserializers to avoid deep wrapper array nesting, when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. |
| CVE-2022-25762 | High | 2022-05-13 | No exploit published | No public exploit | If a web application sends a WebSocket message concurrently with the WebSocket connection closing when running on Apache Tomcat 8.5.0 to 8.5.75 or Apache Tomcat 9.0.0.M1 to 9.0.20, it is possible that the application will continue to use the socket after it has been closed. The error handling triggered in this case could cause the a pooled object to be placed in the pool twice. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors. |
| CVE-2020-36518 | High | 2022-03-11 | No exploit published | No public exploit | jackson-databind before 2.13.0 allows a Java StackOverflow exception and denial of service via a large depth of nested objects. |
| CVE-2021-41079 | High | 2021-09-16 | No exploit published | No public exploit | Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service. |
| CVE-2021-37714 | High | 2021-08-18 | No exploit published | No public exploit | jsoup is a Java library for working with HTML. Those using jsoup versions prior to 1.14.2 to parse untrusted HTML or XML may be vulnerable to DOS attacks. If the parser is run on user supplied input, an attacker may supply content that causes the parser to get stuck (loop indefinitely until cancelled), to complete more slowly than usual, or to throw an unexpected exception. This effect may support a denial of service attack. The issue is patched in version 1.14.2. There are a few available workarounds. Users may rate limit input parsing, limit the size of inputs based on system resources, and/or implement thread watchdogs to cap and timeout parse runtimes. |
| CVE-2021-31684 | High | 2021-06-01 | No exploit published | No public exploit | A vulnerability was discovered in the indexOf function of JSONParserByteArray in JSON Smart versions 1.3 and 2.4 which causes a denial of service (DOS) via a crafted web request. |
| CVE-2020-13936 | High | 2021-03-10 | No exploit published | No public exploit | An attacker that is able to modify Velocity templates may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine versions up to 2.2. |
| CVE-2021-25329 | High | 2021-03-01 | Protected by Waratek | No public exploit | The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. |
| CVE-2021-25122 | High | 2021-03-01 | Protected by Waratek | No public exploit | When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request. |
| CVE-2020-25649 | High | 2020-12-03 | Protected by Waratek | No public exploit | A flaw was found in FasterXML Jackson Databind, where it did not have entity expansion secured properly. This flaw allows vulnerability to XML external entity (XXE) attacks. The highest threat from this vulnerability is data integrity. |
| CVE-2020-13935 | High | 2020-07-14 | Mitigation candidate | Working exploit published | The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. |
| CVE-2020-11996 | High | 2020-06-26 | Mitigation candidate | Proof of concept only | A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive. |
| CVE-2020-9484 | High | 2020-05-20 | Protected by Waratek | Working exploit published | When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. |
