Executive Summary

This vulnerability exists in the Wavlink WL-WN570HA1 R70HA1 V1410_221110 firmware, specifically in the function set_sys_adm within the /cgi-bin/adm.cgi file.

The issue arises from improper handling of the Username argument, which allows an attacker to perform command injection.

This means an attacker can remotely execute arbitrary commands on the device by manipulating the Username parameter.

The vulnerability affects only unsupported products, and the vendor has removed the affected firmware from their website.

Impact Analysis

An attacker exploiting this vulnerability can remotely execute arbitrary commands on the affected device.

This could lead to unauthorized control over the device, potentially allowing the attacker to disrupt network operations, steal data, or use the device as a foothold for further attacks.

Since the affected products are no longer supported, no official patches are available, increasing the risk if the device remains in use.

Mitigation Strategies

The affected firmware version R70HA1 V1410_221110 has been removed from the vendor's website, indicating it is no longer supported.

Immediate mitigation steps include discontinuing the use of the vulnerable Wavlink WL-WN570HA1 devices running this firmware and replacing them with supported devices or firmware versions.
