Title: PHP Crypt Function Authentication Bypass Vulnerability
Severity: MODERATE
Description:
PHP is a general-purpose scripting language that is especially suited for web development and can be embedded into HTML. The 'crypt()' function returns an encrypted string UNIX DES-based encryption algorithms or other private key encryption algorithms.
PHP is prone to an authentication-bypass vulnerability. Specifically, in multi-threaded environments, the 'crypt()' function will use the same internal memory area. A specially timed call to 'crypt()' may return the response of another legitimate call.
An attacker may be able to exploit this issue to retrieve legitmate credentials or possibly bypass authentication.
