Citrix administrators are being warned to take immediate action regarding two zero-day vulnerabilities affecting NetScaler ADC and Gateway appliances that are currently being exploited in the wild. The vulnerabilities pose a significant threat to infrastructure, potentially allowing unauthorized access or remote code execution by malicious actors.
Security professionals recommend following official Citrix security bulletins immediately. If patching is not an option in the short term, organizations are advised to consider taking affected appliances offline to prevent compromise. Monitoring for indicators of compromise (IoCs) is essential for any environment running these NetScaler versions.
