CWE-ID: CWE-352

Exploitation vector: Remote access

Exploit availability: No public exploit available

Vulnerable software:
iCMS

Software vendor:
iCMS

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin in admincp.php?app=members&do=del, when empty CSRF token is passed. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website, such as delete all application users.

Example:

http://[host]/admincp.php?app=members&do=del&id=1&frame=iPHP&CSRF_TOKEN=
