Vulnerability-Lab Team (F0x) discovered a persistent Cross Site Scripting Vulnerability on the OSCommerce Shop Software.
2012-02-02: Public or Non-Public Disclosure
Multiple persistant cross site vulnerabilities are detected on the OSCommerce v3.0.2.
The bug allows remote attacker to implement malicious script code on the application side.
Successful exploitation of the vulnerability allows an attacker to manipulate specific modules & can
lead to session hijacking (user/mod/admin).
Proof of Concept:
The vulnerability can be exploited by local low privileged user account with required medium user inter action. For demonstration or reproduce ...
"'><img src=vul onerror=alert('vulnerabilitylab')> in the "front" field of the shirt module.
Size: Medium<br/>- Front: "'><img src=vul onerror=alert('vulnerabilitylab')>
The security risk of the persistent vulnerability is estimated as medium.
