AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Quick.CMS 6.7 is vulnerable to cross-site scripting via the sDescription parameter in the sliders form, exploitable through CSRF.

Vulnerability

Quick.CMS 6.7 contains a stored cross-site scripting (XSS) vulnerability in the sliders form. An authenticated attacker can inject arbitrary JavaScript via the sDescription parameter when creating or editing a slider. The vulnerability exists in versions up to and including 6.7 [1].

Exploitation

An attacker must first have valid admin credentials. They then craft a CSRF form targeting admin.php?p=sliders-form with a hidden input for sDescription containing an XSS payload such as ``. When an authenticated admin submits the form (e.g., via social engineering), the payload executes in the admin's browser [2].

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the admin panel. This can lead to session hijacking, theft of cookies, or performing administrative actions on behalf of the victim [3].

Mitigation

The vulnerability is fixed in Quick.CMS version 6.8, released on 2025-04-24 [1]. Users should upgrade to version 6.8 or later. No workaround is available for versions 6.7 and earlier.
