Title: Cactusoft CactuShop Lite Remote Arbitrary File Deletion Backdoor Vulnerability
Severity: HIGH
Description:
Cactusoft CactuShop Lite is a web based e-commerce shopping cart system written in ASP. Cactusoft CactuShop Lite is demo software and not intended by the vendor for commercial use.
A vulnerability has been reported to exist in the software that may allow remote attackers to delete arbitrary files on a vulnerable system. The problem is reported to be caused by user-supplied data passed via the 'strEmailAddress' variable of the AddToMailingList() function. It has been reported that the AddToMailingList() function is used to store user e-mail addresses for a mailing list. When a user-supplied e-mail address is provided, the function checks whether the address starts with the '|||' characters. If a valid file name is provided after the '|||' characters instead of an e-mail address, the specified file is deleted from the system.
Successful exploitation of this issue may allow a remote attacker to delete arbitrary files on a vulnerable system, which could result in corruption of files eventually leading to a denial of service issue. This problem is reported to be a backdoor in the software.
Cactusoft CactuShop Lite version 5.0 has been reported to be prone to this issue.
