Discussion
Joomla! F!BB Component SQL Injection and HTML Injection Vulnerabilities
The Joomla! F!BB component is prone to an SQL-injection vulnerability and HTML-injection vulnerabilities because it fails to sufficiently sanitize user-supplied input.
An attacker may leverage the HTML-injection issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials, control how the site is viewed, and launch other attacks.
The attacker may exploit the SQL-injection issue to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
F!BB 1.96 is vulnerable; other versions may also be affected.
