CVE Severity Published▾ Status Exploitation Description
CVE-2020-11979 High 2020-10-01 No exploit published No public exploit As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
CVE-2020-5421 Medium 2020-09-19 No exploit published No public exploit In Spring Framework versions 5.2.0 - 5.2.8, 5.1.0 - 5.1.17, 5.0.0 - 5.0.18, 4.3.0 - 4.3.28, and older unsupported versions, the protections against RFD attacks from CVE-2015-5211 may be bypassed depending on the browser used through the use of a jsessionid path parameter.
CVE-2020-24750 High 2020-09-17 Protected by Waratek No public exploit FasterXML jackson-databind 2.x before 2.9.10.6 mishandles the interaction between serialization gadgets and typing, related to com.pastdev.httpcomponents.configuration.JndiConfiguration.
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-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-2019-10086 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-2019-12086 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-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.
