GitLab 14.1 < 15.6.8 / 15.7 < 15.7.7 / 15.8 < 15.8.2 (CVE-2023-22490)

medium Nessus Plugin ID 171884

Language:

Synopsis

The GitLab instance installed on the remote host is affected by vulnerability.

Description

The version of GitLab installed on the remote host is between 14.1 to 15.6.8, prior to 15.7.7, prior to 15.8.2. It is, therefore, affected by a vulnerability as referenced in the CRITICAL-SECURITY-RELEASE-GITLAB-15-8-2-RELEASED advisory.

- A attacker can create a specially crafted repository, forcing Git into using a specific local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links, the objects directory itself can itself be a symbolic link, allowing access outside the git repository with the authority of the git user. (CVE-2023-22490)

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 15.6.8, 15.7.7, 15.8.2 or later.
