Authenticated remote code execution
Published Jan 17, 2024 · Updated Oct 21, 2025
Code injection in NetScaler ADC and NetScaler Gateway allows remote authenticated users to execute code through the management interface. NetScaler has not disclosed the affected handler, untrusted input, or unsafe code-generation operation. Exploitation requires low-privileged access to an NSIP, CLIP, or SNIP management interface and yields code execution on the appliance.
