Published Jun 9, 2022 · Updated Apr 15, 2025

Privilege escalation in Webyog MONyog Ultimate 6.63 allows remote authenticated users to gain administrative access via forged cookies. The cookie handler trusts client-controlled HasServerEdit and IsAdmin values, allowing either flag to be changed from 0 to 1. A valid normal-user session is required; successful tampering opens administrative functions, including role creation and access to stored setup passwords.
