About this tag
CVE-2019-19781 is a critical vulnerability affecting Citrix Application Delivery Controller, Citrix Gateway, and SD-WAN WANOP appliances. It allows a remote, unauthenticated attacker to perform arbitrary code execution. Exploits have been detected in the wild, and organizations that did not apply mitigations promptly were targeted. Compromised systems cannot be remediated by simply applying software patches; full remediation requires additional steps. CISA has released alerts (AA20-020A and AA20-031A) detailing detection and response measures. Users and administrators should upgrade to fixed firmware versions as soon as possible.
