CVE-2023-32188Network attack vector

Authenticated code execution via recoverable JWT signing certificate

Published Oct 16, 2024 · Updated Oct 16, 2024

Incorrect JWT generation in NeuVector before 5.2.2 allows remote authenticated users to forge tokens and execute arbitrary code. The controller relies on a non-unique JWT-signing certificate recoverable from the software, causing forged tokens to be accepted by Manager and REST API endpoints. A valid low-privileged session and network access to either interface are required; successful forgery grants administrative actions, including custom-compliance-script code execution.
