Citrix demande un correctif immédiat pour une vulnérabilité critique de NetScaler

A vulnerability has been discovered in Citrix NetScaler Application Delivery Controller (ADC) and Citrix NetScaler Gateway that could allow for remote code execution. Citrix NetScaler ADC (Application Delivery Controller) is an enterprise networking platform and traffic management device designed to optimize, secure, and accelerate the delivery of web and cloud applications. Successful exploitation of the most severe of these vulnerabilities could allow attackers to gain remote code execution (RCE) on targeted devices or trigger a denial-of-service state that can cause crashes. To be vulnerable, NetScaler ADC and NetScaler Gateway appliances must be configured as a Security Assertion Markup Language (SAML) Identity Provider (IdP) or Service Provider (SP).
