GitLab 0.0 < 15.6.8 / 15.7 < 15.7.7 / 15.8 < 15.8.2 (CVE-2023-23946)

high Nessus Plugin ID 171883

Language:

Synopsis

The version of GitLab installed on the remote host is affected by a vulnerability.

Description

The version of GitLab installed on the remote host is affected by a vulnerability, as follows:

 - Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to `git apply`, a path outside the working tree can be overwritten as the user who is running `git apply`. A fix has been prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6, v2.31.7, and v2.30.8. As a workaround, use `git apply --stat` to inspect a patch before applying; avoid applying one that creates a symbolic link and then creates a file beyond the symbolic link.
 (CVE-2023-23946)

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.
