Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.277.3 or Jenkins weekly prior to 2.286. It is, therefore, affected by a vulnerability:

 - In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame. (CVE-2021-28165)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Jenkins weekly to version 2.286 or later or Jenkins LTS to version 2.277.3 or later
