Title: Asmax Ar-804gu Router 'script' Remote Arbitrary Shell Command Injection Vulnerability
Severity: CRITICAL
Description:
Asmax Ar-804gu is a router for small or home office users.
The router is prone to a remote command-injection vulnerability because it fails to adequately restrict access to a maintenance script. This issue affects the 'system' parameter of 'cgi-bin/script' of the device's web-based management interface.
Remote attackers can exploit this issue to execute arbitrary shell commands with superuser privileges, which may facilitate a complete compromise of the affected device.
Asmax Ar-804gu with firmware version 66.34.1 is affected; other versions may also be vulnerable.
Affected Products:
- Asmax Ar-804gu Router 66.34.1
