Vulnerabilidades de Xenforo

XenForo before 2.3.10 and before 2.2.19 is vulnerable to stored cross-site scripting (XSS) in structured text mentions, primarily affecting legacy profile post content. An attacker can inject malicious scripts through crafted mentions that are stored and executed when other users view the content.

XenForo before 2.3.9 and before 2.2.18 is vulnerable to cross-site scripting (XSS) related to lightbox usage in posts. An attacker can inject malicious scripts that execute when users interact with post content displayed in the lightbox.

XenForo before 2.3.9 is vulnerable to stored cross-site scripting (XSS) related to BB code rendering. An attacker can inject malicious scripts through BB code that are stored and executed when other users view the content.

XenForo before 2.3.7 allows information disclosure via local account page caching on shared systems. On systems where multiple users share a browser or machine, cached account pages could expose sensitive user information to other local users.

XenForo before 2.2.17 and 2.3.1 allows open redirect via a specially crafted URL. The getDynamicRedirect() function does not adequately validate the redirect target, allowing attackers to redirect users to arbitrary external sites using crafted URLs containing newlines, user credentials, or host mismatches.

Xenforo 2.2.13 contains a stored cross-site scripting vulnerability that allows authenticated administrators to inject malicious scripts through the smilie category title parameter. Attackers can create a smilie category with a malicious script that will execute when the admin panel is loaded, potentially enabling further client-side attacks.
