CVE-2026-8451: awe-125 in NetScaler ADC
Insufficient input validation in NetScaler ADC and NetScaler Gateway leading to memory overread if NetScaler ADC or NetScaler Gateway is configured as a SAML IDP
AI Analysis
Technical Summary
CVE-2026-8451 affects NetScaler ADC and NetScaler Gateway when configured as a SAML IDP. The vulnerability arises from insufficient input validation, causing a memory overread condition. This can potentially expose sensitive information or cause denial of service. The CVSS 4.0 vector indicates the vulnerability is remotely exploitable without privileges or user interaction, with high impact on confidentiality and availability, and low impact on integrity. The affected versions are exactly 13.1 and 14.1. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation of this vulnerability could lead to unauthorized disclosure of memory contents due to memory overread, impacting confidentiality. It may also affect system availability. The vulnerability is remotely exploitable without authentication or user interaction, increasing its risk. There are no known active exploits reported so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider limiting exposure of NetScaler ADC and Gateway configured as SAML IDP to trusted networks and monitoring for unusual activity related to SAML processing.
