| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2023-21971 | Medium | 2023-04-18 | No exploit published | No public exploit | Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions that are affected are 8.0.32 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Connectors as well as unauthorized update, insert or delete access to some of MySQL Connectors accessible data and unauthorized read access to a subset of MySQL Connectors accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:H). |
| CVE-2023-28708 | Medium | 2023-03-22 | No exploit published | No public exploit | When using the RemoteIpFilter with requests received from a reverse proxy via HTTP that include the X-Forwarded-Proto header set to https, session cookies created by Apache Tomcat 11.0.0-M1 to 11.0.0.-M2, 10.1.0-M1 to 10.1.5, 9.0.0-M1 to 9.0.71 and 8.5.0 to 8.5.85 did not include the secure attribute. This could result in the user agent transmitting the session cookie over an insecure channel. Older, EOL versions may also be affected. |
| CVE-2022-41915 | Medium | 2022-12-13 | No exploit published | Proof of concept only | Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling `DefaultHttpHeadesr.set` with an _iterator_ of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the `DefaultHttpHeaders.set(CharSequence, Iterator<?>)` call, into a `remove()` call, and call `add()` in a loop over the iterator of values. |
| CVE-2021-37533 | Medium | 2022-12-03 | No exploit published | No public exploit | Prior to Apache Commons Net 3.9.0, Net's FTP client trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client. The default in version 3.9.0 is now false to ignore such hosts, as cURL does. See https://issues.apache.org/jira/browse/NET-711. |
| CVE-2022-38752 | Medium | 2022-09-05 | Protected by Waratek | Proof of concept only | Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack-overflow. |
| CVE-2022-38751 | Medium | 2022-09-05 | No exploit published | No public exploit | Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. |
| CVE-2022-38750 | Medium | 2022-09-05 | No exploit published | No public exploit | Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. |
| CVE-2022-38749 | Medium | 2022-09-05 | No exploit published | No public exploit | Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. |
| CVE-2022-36033 | Medium | 2022-08-29 | Protected by Waratek | Proof of concept only | jsoup is a Java HTML parser, built for HTML editing, cleaning, scraping, and cross-site scripting (XSS) safety. jsoup may incorrectly sanitize HTML including `javascript:` URL expressions, which could allow XSS attacks when a reader subsequently clicks that link. If the non-default `SafeList.preserveRelativeLinks` option is enabled, HTML including `javascript:` URLs that have been crafted with control characters will not be sanitized. If the site that this HTML is published on does not set a Content Security Policy, an XSS attack is then possible. This issue is patched in jsoup 1.15.3. Users should upgrade to this version. Additionally, as the unsanitized input may have been persisted, old content should be cleaned again using the updated version. To remediate this issue without immediately upgrading: - disable `SafeList.preserveRelativeLinks`, which will rewrite input URLs as absolute URLs - ensure an appropriate [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) is defined. (This should be used regardless of upgrading, as a defence-in-depth best practice.) |
| CVE-2022-34305 | Medium | 2022-06-23 | Protected by Waratek | Exploited | In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the Form authentication example in the examples web application displayed user provided data without filtering, exposing a XSS vulnerability. |
| CVE-2022-22971 | Medium | 2022-05-12 | Protected by Waratek | No public exploit | In spring framework versions prior to 5.3.20+ , 5.2.22+ and old unsupported versions, application with a STOMP over WebSocket endpoint is vulnerable to a denial of service attack by an authenticated user. |
| CVE-2022-22970 | Medium | 2022-05-12 | No exploit published | No public exploit | In spring framework versions prior to 5.3.20+ , 5.2.22+ and old unsupported versions, applications that handle file uploads are vulnerable to DoS attack if they rely on data binding to set a MultipartFile or javax.servlet.Part to a field in a model object. |
| CVE-2022-23437 | Medium | 2022-01-24 | No exploit published | No public exploit | There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions. |
| CVE-2021-44832 | Medium | 2021-12-28 | Protected by Waratek | Exploited | Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. |
| CVE-2021-36374 | Medium | 2021-07-14 | No exploit published | No public exploit | When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected. |
| CVE-2021-30129 | Medium | 2021-07-12 | No exploit published | No public exploit | A vulnerability in sshd-core of Apache Mina SSHD allows an attacker to overflow the server causing an OutOfMemory error. This issue affects the SFTP and port forwarding features of Apache Mina SSHD version 2.0.0 and later versions. It was addressed in Apache Mina SSHD 2.7.0 |
| CVE-2020-6950 | Medium | 2021-06-02 | Protected by Waratek | Working exploit published | Directory traversal in Eclipse Mojarra before 2.3.14 allows attackers to read arbitrary files via the loc parameter or con parameter. |
| CVE-2021-29425 | Medium | 2021-04-13 | Protected by Waratek | No public exploit | In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value. |
| CVE-2021-27568 | Medium | 2021-02-23 | Protected by Waratek | No public exploit | An issue was discovered in netplex json-smart-v1 through 2015-10-23 and json-smart-v2 through 2.4. An exception is thrown from a function, but it is not caught, as demonstrated by NumberFormatException. When it is not caught, it may cause programs using the library to crash or expose sensitive information. |
| CVE-2020-17521 | Medium | 2020-12-07 | Protected by Waratek | No public exploit | Apache Groovy provides extension methods to aid with creating temporary directories. Prior to this fix, Groovy's implementation of those extension methods was using a now superseded Java JDK method call that is potentially not secure on some operating systems in some contexts. Users not using the extension methods mentioned in the advisory are not affected, but may wish to read the advisory for further details. Versions Affected: 2.0 to 2.4.20, 2.5.0 to 2.5.13, 3.0.0 to 3.0.6, and 4.0.0-alpha-1. Fixed in versions 2.4.21, 2.5.14, 3.0.7, 4.0.0-alpha-2. |
| CVE-2020-15250 | Medium | 2020-10-12 | Protected by Waratek | No public exploit | In JUnit4 from version 4.7 and before 4.13.1, the test rule TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. This vulnerability impacts you if the JUnit tests write sensitive information, like API keys or passwords, into the temporary folder, and the JUnit tests execute in an environment where the OS has other untrusted users. Because certain JDK file system APIs were only added in JDK 1.7, this this fix is dependent upon the version of the JDK you are using. For Java 1.7 and higher users: this vulnerability is fixed in 4.13.1. For Java 1.6 and lower users: no patch is available, you must use the workaround below. If you are unable to patch, or are stuck running on Java 1.6, specifying the `java.io.tmpdir` system environment variable to a directory that is exclusively owned by the executing user will fix this vulnerability. For more information, including an example of vulnerable code, see the referenced GitHub Security Advisory. |
| CVE-2019-12415 | Medium | 2019-10-23 | Protected by Waratek | No public exploit | In Apache POI up to 4.1.0, when using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents, a specially crafted document can allow an attacker to read files from the local filesystem or from internal network resources via XML External Entity (XXE) Processing. |
| CVE-2019-17091 | Medium | 2019-10-02 | Protected by Waratek | No public exploit | faces/context/PartialViewContextImpl.java in Eclipse Mojarra, as used in Mojarra for Eclipse EE4J before 2.3.10 and Mojarra JavaServer Faces before 2.2.20, allows Reflected XSS because a client window field is mishandled. |
