CVE-2018-15681
Due to the weak and predictable salt that is in place, an attacker who successfully steals this cookie can efficiently brute-force it to retrieve the user's cleartext password.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in BTITeam XBTIT 2.5.4. When a user logs in, their password hash is rehashed using a predictable salt and stored in the "pass" cookie, which is not flagged as HTTPOnly. Due to the weak and predictable salt that is in place, an attacker who successfully steals this cookie can efficiently brute-force it to retrieve the user's cleartext password.
