Vulnerability Information

Severity: Critical
Vulnerability Published: 2022-03-31
Patch Published: 2022-03-31
CVE [?]: CVE-2022-1162
CPE [?]: cpe:/a:gitlab:gitlab

Synopsis

A source control application running on the remote web server has a hard-coded password .

Description

A hardcoded password was set for accounts registered using an OmniAuth provider (e.g. OAuth, LDAP, SAML) in GitLab CE/EE versions 14.7 prior to 14.7.7, 14.8 prior to 14.8.5, and 14.9 prior to 14.9.2 allowing attackers to potentially take over accounts.

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 14.7.7, 14.8.5, 14.9.2, or later.

How to Run

Here is how to run the GitLab 14.7.x < 14.7.7 / 14.8.x < 14.8.5 / 14.9.x < 14.8.2 Default Password as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select CGI abuses plugin family.
On the right side table select GitLab 14.7.x < 14.7.7 / 14.8.x < 14.8.5 / 14.9.x < 14.8.2 Default Password plugin ID 159830.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl gitlab_cve-2022-1162.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a gitlab_cve-2022-1162.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - gitlab_cve-2022-1162.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state gitlab_cve-2022-1162.nasl -t <IP/HOST>

Go back to menu.
