Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS : CiviCRM vulnerability (USN-8242-1)

medium Nessus Plugin ID 314223

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8242-1 advisory.

 Takuya Aramaki discovered that Smarty, vendored in CiviCRM, did not properly escape JavaScript code. An attacker could possibly use this issue to conduct a cross-site scripting attack.

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 packages.
