Some vulnerabilities have been reported in Easy Scripts Answer and Question Script, which can be exploited by malicious users to bypass certain security restrictions and by malicious people to conduct cross-site scripting attacks.
1) Input passed to the "questionid" parameter in questiondetail.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.
2) Input passed to the "userid" parameter in myaccount.php is not properly verified before being used to load the user account. This can be exploited to view and modify other accounts by specifying the another user's ID.
Successful exploitation requires a valid user credentials.
Solution: Edit the source code to ensure that input is properly sanitised and verified.
