CVE-2023-27055Public exploitNetwork attack vector

File disclosure via unfiltered request-path traversal

Published Mar 24, 2023 · Updated Feb 21, 2025

Path traversal in AVer PTZApp2 before 2.0.1051.53 allows remote attackers to read sensitive local files via crafted GET requests. The local web application on TCP port 36680 accepts traversal sequences in the request target without adequately filtering or validating the supplied path. No authentication or user interaction is required; successful requests disclose files readable by the service, including its public and private keys.
