NETGEAR · ProSAFE Network Management System

Summary

A command injection flaw in the NETGEAR ProSAFE Network Management System, specifically within the SettingConfigController class, where the fileName parameter is passed to a system call without proper validation of user-supplied input. An attacker with network access can exploit it by first bypassing the product's authentication mechanism (or holding low-privileged credentials), then sending a crafted request to execute arbitrary code in the context of SYSTEM, with no user interaction required.

Official description · CVE.org

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR ProSAFE Network Management System 1.6.0.26. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the SettingConfigController class. When parsing the fileName parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-12121.
