Laurent Gaffié and Benjamin Mossé have reported some vulnerabilities in JiRo's Link Manager, which can be exploited by malicious people to conduct script insertion and SQL injections attacks.
1) Input passed to the "LinkID" parameter in openlink.asp and to the "CategoryID" parameter in viewlinks.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.
2) Input passed to the "lName", "lUrl", "lImage", and "lDescription" parameter in submitlink.asp is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site when malicious data is viewed.
Solution: Edit the source code to ensure that input is properly verified.
