Gestsup before 3.2.10 allows account takeover through the password recovery functionality (remote). The affected component is the file forgot_pwd.php - it uses a weak algorithm for the generation of password recovery tokens (the PHP uniqueid function), allowing a brute force attack.
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Common protection mechanisms include:
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
