Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : mod-wsgi vulnerability (USN-5551-1)

high Nessus Plugin ID 163860

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5551-1 advisory.

It was discovered that mod-wsgi did not correctly remove the X-Client-IP header when processing requests from untrusted proxies. A remote attacker could use this issue to pass the header to WSGI applications, contrary to expectations.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libapache2-mod-wsgi and / or libapache2-mod-wsgi-py3 packages.
