Eclipse Jetty Privilege Escalation Vulnerability (Linux)

Eclipse Jetty is prone to a privilege escalation vulnerability through a local temp directory.

On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

Eclipse Jetty version 9.4.32.v20200930 and prior, 10.0.0.beta2 and prior and 11.0.0.beta2 and prior.

Checks if a vulnerable version is present on the target host.

Update to version 9.4.33.v20201020, 10.0.0.beta3, 11.0.0.beta3 or later.
