Critical NetScaler Flaw Can Bypass Authentication on Certain Gateway and AAA Servers

Citrix has released security updates to address two critical vulnerabilities in NetScaler ADC and NetScaler Gateway, including a high-severity authentication bypass. These flaws primarily affect deployments where specific configurations are in place, such as using SAML actions and certain gateway or AAA server setups. While no active exploitation has been reported, the vulnerabilities represent a significant risk due to their potential for attackers to gain unauthorized access.
