Synopsis

A source control application running on the remote web server is affected by a denial of service vulnerability.

Description

A potential DOS vulnerability was discovered in GitLab CE/EE affecting all versions from 13.1 prior to 14.7.7, 14.8.0 prior to 14.8.5, and 14.9.0 prior to 14.9.2. The api to update an asset as a link from a release had a regex check which caused exponential number of backtracks for certain user supplied values resulting in high CPU usage.

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

Solution

Upgrade to GitLab version 14.7.7, 14.8.5, 14.9.2, or later.
