CVE-2021-23855

The user and password data base is exposed by an unprotected web server resource. Passwords are hashed with a weak hashing algorithm and therefore allow an attacker to determine the password by using rainbow tables.

CVE-2021-23857

Login with hash: The login routine allows the client to log in to the system not by using the password, but by using the hash of the password. Combined with CVE-2021-23858, this allows an attacker to subsequently login to the system.
