netscaler-adc

Predictable exact value from previous values 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.

This vulnerability, identified as CWE-342 (Predictable exact value from previous values), affects Citrix NetScaler ADC and Gateway products. Versions before 14.1-73.37 and 13.1-64.23 for ADC and Gateway are vulnerable, including FIPS and NDcPP variants. The issue allows an attacker to predict exact values based on previous values, which may compromise security properties. The CVSS 4.0 base score is 8.8, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability.

CVE-2026-88778: CWE-342 Predictable exact value from previous values in Citrix NetScaler ADC

Denial of service via malformed HTTP/2 requests in NetScaler ADC and NetScaler Gateway if HTTP/2 is enabled in HTTP Profile and associated with the virtual server (of type LB, CS, VPN) or the service configured on NetScaler

This vulnerability (CVE-2026-13474) affects NetScaler ADC and NetScaler Gateway products when HTTP/2 is enabled in the HTTP Profile and linked to virtual servers of type load balancing (LB), content switching (CS), VPN, or the configured services. Malformed HTTP/2 requests can cause a denial of service due to improper memory management, specifically a missing release of memory after its effective lifetime (CWE-401). The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on availability. No official patch or remediation level has been provided by the vendor as of the published date.
