GitLab 8.4 < 14.4.5 / 14.5.0 < 14.5.3 / 14.6.0 < 14.6.3 Incorrect Port Validation

medium Nessus Plugin ID 159959

Language:

Synopsis

A source control application running on the remote web server is affected by an incorrect port validation vulnerability.

Description

According to its self-reported version, the instance of GitLab running on the remote web server is 8.4 prior to 14.4.5, 14.5.0 prior to 14.5.3, or 14.6.0 prior to 14.6.3. It is, therefore, affected by an incorrect port validation issue which could fail to protect against attacks sending requests to localhost on ports 80 and 443 if Gitlab was configured to run on a port other that 80 or 443.

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 14.4.5 / 14.5.3 / 14.6.3 or later.
