Remote unauthenticated exploitation of NetScaler ADC and NetScaler Gateway allows attackers to cause high availability impact against the appliance alongside limited confidentiality and integrity compromise, without any privileges or user interaction. Affected builds span versions 13.1 through build 63.21 and 14.1 through build 73.32 for both products. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the combination of network-accessible attack vector with zero authentication barrier on widely deployed perimeter appliances warrants prompt remediation.
An insufficient input validation vulnerability exists in Citrix NetScaler ADC and NetScaler Gateway when configured as a SAML Identity Provider, allowing attackers to trigger a memory overread condition. The vulnerability affects both the NetScaler ADC and NetScaler Gateway products across multiple versions, and successful exploitation could lead to information disclosure by reading adjacent memory contents. While no CVSS score or EPSS data is currently published, the CWE-125 classification (Out-of-bounds Read) combined with the SAML IDP configuration context suggests moderate to high real-world risk for organizations relying on these devices for identity management.
Citrix NetScaler ADC and Gateway instances configured for SSL VPN, ICA Proxy, CVPN, RDP Proxy, or AAA virtual servers are vulnerable to a race condition that enables authenticated attackers to hijack other users' sessions. An attacker with valid credentials can exploit timing-dependent conditions to cause session mixup between concurrent users, potentially gaining unauthorized access to sensitive resources or impersonating other authenticated users. No patch is currently available for this high-severity vulnerability.
