The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.277.x prior to 2.277.43.0.6, 2.303.x prior to 2.303.30.0.5, or 2.x prior to 2.319.3.3. It is, therefore, affected by multiple vulnerabilities:
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible.
Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible. (CVE-2021-43859)
Jenkins 2.333 and earlier, LTS 2.319.2 and earlier defines custom XStream converters that have not been updated to apply the protections for the vulnerability CVE-2021-43859 and allow unconstrained resource usage. (CVE-2022-0538)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
