CVE-2026-79577 Details
Description
An issue in the /cas/login component of sso-master v1.0.0 allows attackers to authenticate into the application without a password via sending a crafted POST request.
A vulnerability in the sso-master application version 1.0.0 allows attackers to authenticate as an admin without a password. This is achieved by sending a crafted POST request to the CAS login endpoint. The vulnerability arises because the authentication handler for this login flow includes a hardcoded success condition for the admin user when the 'system' parameter is set to 'sso', bypassing password verification entirely.
