CVE-2016-10213
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA10 AX1030 and possibly other devices with software before 2.7.2-P8 uses random GCM nonce generations, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe A10 AX1030 and related devices running software before version 2.7.2-P8 implement flawed random nonce generation for GCM (Galois/Counter Mode) encryption. When GCM nonces are reused or generated with insufficient randomness, an attacker can perform a 'forbidden attack' that leaks the authentication key, enabling data spoofing within the session.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the ACOS software versionAccess the device CLI and run 'show version' or check through the web management interface to display the currently installed Advanced Core Operating System version.Affected if The displayed version is 2.7.2 or any earlier version (for example, 2.7.1, 2.7.0, or older releases).
-
Locate GCM encryption configurationExamine the device's SSL/TLS or encryption configuration settings through the CLI command 'show ssl' or via the web interface under the SSL proxy or virtual server configuration sections.Affected if GCM (Galois/Counter Mode) cipher suites such as AES-GCM are listed as enabled or selected for any SSL/TLS virtual server or proxy configuration.
-
Verify GCM is actively in useReview active connection statistics or session data using 'show ssl stats' or by monitoring live traffic to confirm that GCM cipher suites are being negotiated and used for encrypted sessions.Affected if Connections are actively using GCM-based cipher suites and the device version is 2.7.2 or earlier.
You are affected if your device runs ACOS version 2.7.2 or earlier and has GCM encryption enabled or actively used in any SSL/TLS configuration.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade affected devices to software version 2.7.2-P8 or later, which implements proper GCM nonce generation. After upgrading, consider rotating encryption keys as a precautionary measure.
