Title
Improper Multi-Factor Authentication Validation Allows Authentication Bypass
Summary
Incorrect authentication vulnerability in the TSplus Remote Access multi-factor authentication (MFA) mechanism. A remote attacker authenticated with valid first-factor credentials could bypass the second-factor verification because the authentication flow does not correctly apply the MFA validation result, allowing the attacker to complete the login without a valid second-factor token and gain access to protected applications and resources.
