CVE-2017-5933: n/a vulnerability

CVE-2017-5933: Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11....

Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11.1 before Build 51.21 randomly generates GCM nonces, which makes it marginally easier for remote attackers to obtain the GCM authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270.

Security readout for executives and security teams

Older Citrix NetScaler ADC and NetScaler Gateway builds used random AES-GCM nonces. If a nonce repeats in a session, an attacker may have an easier path to spoof protected data. This is mainly a legacy exposure issue: organizations still running the listed 10.5, 11.0, or 11.1 builds should prioritize upgrade validation. Exposure is likely limited to organizations still operating Citrix NetScaler ADC or NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, or 11.1 before Build 51.21, especially on internet-facing gateway services. Treat this as a targeted legacy platform cleanup item, not a confirmed active incident. If any affected NetScaler Gateway or ADC remains externally exposed, remediation should be scheduled promptly because the issue affects cryptographic integrity on edge infrastructure. Mitigation focus: Upgrade affected Citrix NetScaler ADC/Gateway builds to the listed fixed builds or later.; Confirm current vendor guidance in Citrix CTX220329 before remediation planning.; Prioritize internet-facing NetScaler Gateway and ADC systems first..
