The version of GitLab installed on the remote host is affected by a vulnerability, as follows:
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.Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
