CVE-2022-23332Public exploitNetwork attack vector

Authenticated command execution via Manual Ping field

Published May 9, 2022 · Updated Aug 3, 2024

Command injection in the Manual Ping web UI of Ejoin ACOM508, ACOM516, and ACOM532 gateways allows remote authenticated users to execute commands. The form passes its field value into the device's ping command without neutralizing shell syntax; the public proof of concept splits payloads into five strings. Access to the web interface with low privileges is required, and successful injection can open a reverse shell with control over the gateway.
