Multiple vulnerabilities have been reported in 2daybiz Online Classified Script, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.
1) Input passed via the "sid" parameter to headersearch.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Note: This may also be exploited to conduct limited SQL injection attacks.
2) Input passed via the "cid" parameter to categorysearch.php is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Note: This can further be exploited to conduct cross site scripting attacks via SQL error messages.
3) Input passed via the "vid" parameter to searchview.php is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Solution: Filter malicious characters and character sequences using a proxy.
