Citrix released patches for NetScaler and Secure Access Client vulnerabilities that could bypass authentication, disrupt services or elevate user privileges, The Hacker News reported. A NetScaler Console flaw allows an unauthenticated attacker to access restricted appliance resources; Windows and Linux client flaws let low-privileged users gain SYSTEM or root privileges.

The Console fix is available in version 14.1-74.34 and later. Client fixes are available in Windows version 26.11.1.6 and Linux version 26.10.4 and later. Separate NetScaler ADC and Gateway fixes address memory flaws, with exposure depending on deployment configuration. Citrix said it was unaware of exploits for the announced vulnerabilities.
