Vulnerabilities

A Stored Cross-Site Scripting (XSS) vulnerability exists in the PluXml article comments feature for PluXml versions 5.8.22 and earlier. The application fails to properly sanitize or validate user-supplied input in the "link" field of a comment. An attacker can inject arbitrary JavaScript code using a element. The injected payload is stored in the database and subsequently rendered in the Administration panel's "Comments" section when administrators review submitted comments. Importantly, the malicious script is not reflected in the public-facing comments interface, but only within the backend administration view. Alternatively, users of Administrator, Moderator, Manager roles can also directly input crafted payloads into existing comments. This makes the vulnerability a persistent XSS issue targeting administrative users. This affects /core/admin/comments.php, while CVE-2022-24585 affects /core/admin/comment.php, a uniquely distinct vulnerability.

PluXml CMS is vulnerable to Stored XSS in Static Pages editing functionality. Attacker with editing privileges can inject arbitrary HTML and JS into website, which will be rendered/executed when visiting edited page. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only versions 5.8.21 and 5.9.0-rc7 were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

A vulnerability was determined in PluXml up to 5.8.22. Affected is the function FileCookieJar::__destruct of the file core/admin/medias.php of the component Media Management Module.
