Title: Aztech ADSL2/2+ 4 Port Router Remote Command Injection Vulnerability

Severity: CRITICAL

Description:

Aztech ADSL2/2+ 4 Port Router is a managed router.

The device is prone to a remote command-injection vulnerability via its web interface because it fails to adequately sanitize user-supplied input data.

Remote attackers can exploit this issue by passing 'system()' calls along with shell commands via the 'script' parameter of the 'cgi-bin/script' binary.

Attackers can exploit this issue to execute arbitrary commands, facilitating the remote compromise of affected devices.

Aztech ADSL2/2+ 4 Port Router with firmware 3.7.0 is vulnerable; other versions may also be affected.

Affected Products:

  • Aztech ADSL2/2+ 4 Port 3.7.0
