CVE Severity Published▾ Status Exploitation Description
CVE-2020-10878 High 2020-06-05 Outside Waratek scope No public exploit Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.
CVE-2020-13434 Medium 2020-05-24 Not applicable No public exploit SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.
CVE-2020-11971 High 2020-05-14 No exploit published No public exploit Apache Camel's JMX is vulnerable to Rebind Flaw. Apache Camel 2.22.x, 2.23.x, 2.24.x, 2.25.x, 3.0.0 up to 3.1.0 is affected. Users should upgrade to 3.2.0.
CVE-2018-1285 Critical 2020-05-11 Outside Waratek scope No public exploit Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files.
CVE-2020-11022 Medium 2020-04-29 Outside Waratek scope Exploited In jQuery starting with 1.12.0 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
CVE-2020-9488 Low 2020-04-27 Outside Waratek scope No public exploit Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1
CVE-2020-11612 High 2020-04-07 Outside Waratek scope No public exploit The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
CVE-2020-5245 High 2020-02-24 No exploit published Proof of concept only Dropwizard-Validation before 1.3.19, and 2.0.2 may allow arbitrary code execution on the host system, with the privileges of the Dropwizard service account, by injecting arbitrary Java Expression Language expressions when using the self-validating feature. The issue has been fixed in dropwizard-validation 1.3.19 and 2.0.2.
CVE-2020-7226 High 2020-01-24 No exploit published No public exploit CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data.
CVE-2019-12399 High 2020-01-14 No exploit published No public exploit When Connect workers in Apache Kafka 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.2.0, 2.2.1, or 2.3.0 are configured with one or more config providers, and a connector is created/updated on that Connect cluster to use an externalized secret variable in a substring of a connector configuration property value, then any client can issue a request to the same Connect cluster to obtain the connector's task configuration and the response will contain the plaintext secret rather than the externalized secrets variables.
CVE-2019-14862 Medium 2020-01-02 Outside Waratek scope No public exploit There is a vulnerability in knockout before version 3.5.0-beta, where after escaping the context of the web application, the web application delivers data to its users along with other trusted dynamic content, without validating it.
CVE-2019-16789 High 2019-12-26 Not applicable No public exploit In Waitress through version 1.4.0, if a proxy server is used in front of waitress, an invalid request may be sent by an attacker that bypasses the front-end and is parsed differently by waitress leading to a potential for HTTP request smuggling. Specially crafted requests containing special whitespace characters in the Transfer-Encoding header would get parsed by Waitress as being a chunked request, but a front-end server would use the Content-Length instead as the Transfer-Encoding header is considered invalid due to containing invalid characters. If a front-end server does HTTP pipelining to a backend Waitress server this could lead to HTTP request splitting which may lead to potential cache poisoning or unexpected information disclosure. This issue is fixed in Waitress 1.4.1 through more strict HTTP field validation.
CVE-2019-18276 High 2019-11-28 Not applicable Proof of concept only An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected.
CVE-2019-17195 Critical 2019-10-15 Outside Waratek scope Proof of concept only Connect2id Nimbus JOSE+JWT before v7.9 can throw various uncaught exceptions while parsing a JWT, which could result in an application crash (potential information disclosure) or a potential authentication bypass.
CVE-2019-3740 Medium 2019-09-18 Outside Waratek scope No public exploit RSA BSAFE Crypto-J versions prior to 6.2.5 are vulnerable to an Information Exposure Through Timing Discrepancy vulnerabilities during DSA key generation. A malicious remote attacker could potentially exploit those vulnerabilities to recover DSA keys.
CVE-2019-10086 High 2019-08-20 Protected by Waratek No public exploit In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean.
CVE-2019-13565 High 2019-07-26 Not applicable No public exploit An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user.
CVE-2019-12086 High 2019-05-17 Protected by Waratek No public exploit A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.
CVE-2019-3799 Medium 2019-05-06 Protected by Waratek Working exploit published Spring Cloud Config, versions 2.1.x prior to 2.1.2, versions 2.0.x prior to 2.0.4, and versions 1.4.x prior to 1.4.6, and older unsupported versions allow applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or attacker, can send a request using a specially crafted URL that can lead a directory traversal attack.
CVE-2019-0227 High 2019-05-01 Outside Waratek scope Working exploit published A Server Side Request Forgery (SSRF) vulnerability affected the Apache Axis 1.4 distribution that was last released in 2006. Security and bug commits commits continue in the projects Axis 1.x Subversion repository, legacy users are encouraged to build from source. The successor to Axis 1.x is Axis2, the latest version is 1.7.9 and is not vulnerable to this issue.
CVE-2018-11212 Medium 2018-05-16 Not applicable No public exploit An issue was discovered in libjpeg 9a and 9d. The alloc_sarray function in jmemmgr.c allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted file.
CVE-2017-1000353 Critical 2018-01-29 Protected by Waratek Exploited Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an unauthenticated remote code execution. An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java `SignedObject` object to the Jenkins CLI, that would be deserialized using a new `ObjectInputStream`, bypassing the existing blacklist-based protection mechanism. We're fixing this issue by adding `SignedObject` to the blacklist. We're also backporting the new HTTP CLI protocol from Jenkins 2.54 to LTS 2.46.2, and deprecating the remoting-based (i.e. Java serialization) CLI protocol, disabling it by default.
