Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
