Vulnerability from github – Published: 2024-01-31 12:30 – Updated: 2024-01-31 12:30

Details

SSL connections to NOVELL and Synology LDAP server are vulnerable to a man-in-the-middle attack due to improper certificate validation in AREAL Topkapi Vision (Server). This allows a remote unauthenticated attacker to gather sensitive information and prevent valid users from login.

Severity

9.1 (Critical)
