HIS WebShop "t" Parameter Arbitrary File Disclosure Vulnerability
Description
A vulnerability has been identified in HIS WebShop, which could be exploited by attackers to gain unauthorized access to arbitrary files on a vulnerable system. This issue is due to an input validation error in the "cgi-bin/his-webshop.pl" script that does not validate the "t" parameter, which could be exploited to display the contents of arbitrary files via directory traversal attacks.
