medium Nessus Plugin ID 178106

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has a package installed that is affected by a vulnerability as referenced in the USN-6210-1 advisory.

 It was discovered that Doorkeeper incorrectly performed authorization checks for public clients that have been previous approved. An attacker could potentially exploit these in order to impersonate another user and obtain sensitive information.

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
