Discussion

BLOG:CMS Comment Editing HTML Injection Vulnerability

BLOG:CMS is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would run in the context of the affected website, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user.

Versions prior to BLOG:CMS 4.2.1e are vulnerable.
