Discussion
RETIRED: Simple Machines Forum Censored Words HTML Injection Vulnerability
Simple Machines Forum is prone to an HTML-injection vulnerability because the application 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 browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
Simple Machines Forum 1.1.7 is vulnerable; other versions may also be affected.
NOTE: This BID is being retired because an attacker needs administrative access to an affected application to exploit this issue. An attacker with such access would be able to compromise the application without having to exploit any issue.
