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.


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. 


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:

In user.class.php add this at line 227:
