Discussion

phpBB Avatar Upload HTML Injection Vulnerability

phpBB is prone to an HTML-injection vulnerability. The application fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing an attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.

This issue occurs only when using Microsoft Internet Explorer.
