Vulnerability from cvelistv5 – Published: 2018-12-03 22:00 – Updated: 2024-09-16 21:56

Summary

An exploitable command injection vulnerability exists in the way Netgate pfSense CE 2.4.4-RELEASE processes the parameters of a specific POST request. The attacker can exploit this and gain the ability to execute arbitrary commands on the system. An attacker needs to be able to send authenticated POST requests to the administration web interface. Command injection is possible in the `powerd_ac_mode` POST parameter parameter.

Severity

7.2 (High)
