Secunia

Some vulnerabilities have been reported in OpenAutoClassifieds, which can be exploited by malicious people to bypass certain security restrictions and conduct cross-site scripting or SQL injection attacks.

1) Input passed to the "listing" parameter in friendmail.php is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Input passed to the "id" parameter in listings.php, the username field when logging in, and an unspecified parameter is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) An unspecified error within the admin section can be exploited to bypass certain security restrictions. No more information is currently available.
