Summary

php-cas vulnerability

Details

USN-6913-1 fixed CVE-2022-39369 for Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. This update provides the corresponding fix for Ubuntu 16.04 LTS.

Original advisory details:

Filip Hejsek discovered that phpCAS was using HTTP headers to determine the service URL used to validate tickets. A remote attacker could possibly use this issue to gain access to a victim's account on a vulnerable CASified service.

This security update introduces an incompatible API change. After applying this update, third party applications need to be modified to pass in an additional service base URL argument when constructing the client class.

For more information please refer to the section "Upgrading 1.5.0 -> 1.6.0" of the phpCAS upgrading document:
