CVE-2024-1528Network attack vector

Session hijacking via unencoded module parameters

Published Mar 12, 2024 · Updated Aug 1, 2024

Cross-site scripting in CMS Made Simple 2.2.14 allows remote attackers to partially hijack authenticated browser sessions via crafted links. The /admin/moduleinterface.php handler returns multiple user-controlled parameters without sufficient output encoding, allowing injected JavaScript to execute in the authenticated user's browser. Exploitation requires the targeted user to be authenticated and to interact with the attacker-supplied request; reported impact is limited to partial browser-session hijacking.
