CVE-2023-4249Network attack vector

Authenticated command execution via network-request handling

Published Nov 8, 2023 · Updated Jan 16, 2025

Command injection in Zavio IP Cameras with firmware M2.1.6.05 allows remote authenticated users to execute commands via network requests. The advisory attributes the flaw to device binaries and network-request handling but does not identify the affected binary, request field, or unsafe operation. Low-privileged access is required; successful exploitation permits command execution with camera confidentiality, integrity, and availability impact.
