CVE-2023-22280Network attack vector

Administrator command execution via undisclosed management input

Published Jan 17, 2023 · Updated Apr 4, 2025

OS command injection in the management screen of MAHO-PBX NetDevancer before 1.11.00 allows remote authenticated users to execute OS commands. Public vendor and JVN materials do not identify the affected management action, input parameter, or command-building operation. Administrator privileges and network access to the management screen are required; successful exploitation runs arbitrary commands on the PBX host.
