Title
Critical Pre-Authentication Vulnerability in BeyondTrust Remote Support and Privileged Remote Access
Summary
A critical pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support and Privileged Remote Access. Improper validation of authentication data may allow a network-positioned attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges. Exploitation requires a specific authentication configuration to be enabled
