Executive Summary

This vulnerability exists in the TRENDnet TEW-800MB 1.0.1.0 device, specifically in the function sub_F934 of the file NTPSyncWithHost.cgi. It allows an attacker to perform command injection remotely, meaning they can execute arbitrary commands on the device by exploiting this flaw.

Impact Analysis

The vulnerability can allow a remote attacker to execute arbitrary commands on the affected device, potentially leading to unauthorized control, data compromise, disruption of services, or further attacks within the network.

Detection Guidance

This vulnerability can be detected by monitoring requests to the /NTPSyncWithHost.cgi endpoint on the TRENDnet TEW-800MB router firmware version 1.0.1.0. Detection involves checking for unusual or unauthorized commands executed via this endpoint, especially those that may indicate command injection attempts. Since the exploit requires authentication or a valid CSRF token, inspecting logs for suspicious POST requests to /NTPSyncWithHost.cgi with unusual payloads could help. Specific commands are not provided in the resources, but network monitoring tools or web application firewalls can be configured to alert on such requests. [1, 2]

Mitigation Strategies

Immediate mitigation steps include replacing the affected TRENDnet TEW-800MB device, as no known countermeasures or patches are available. Since the vendor did not respond or provide any fixes, discontinuing use of the vulnerable firmware version 1.0.1.0 and isolating the device from untrusted networks is recommended to reduce exposure. Additionally, restricting access to the /NTPSyncWithHost.cgi endpoint and monitoring for exploitation attempts can help mitigate risk until replacement. [2]
