Multiple vulnerabilities have been reported in Pre Classified Listings ASP, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.
1) Input passed via "address" form field in signup.asp when registering as a new user is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
2) Input passed via the "email" form field to signup.asp and via the "siteid" parameter to detailad.asp 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: Edit the source code to ensure that input is properly sanitised.
