Synopsis

The GitLab instance installed on the remote host is affected by a denial of service vulnerability.

Description

The version of GitLab installed on the remote host is prior to 15.5.7, 15.6.4, 15.7.2. It is, therefore, affected by a denial of service vulnerability as referenced in the SECURITY-RELEASE-GITLAB-15-7-2-RELEASED advisory.

- An issue has been discovered in GitLab CE/EE affecting all versions starting from 10.8 before 15.5.7, all versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. An attacker may cause Denial of Service on a GitLab instance by exploiting a regex issue in how the application parses user agents. (CVE-2022-4131)

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 15.5.7, 15.6.4, 15.7.2 or later.
