Stack-based Buffer Overflow in TRENDnet TEW-827DRU Devices

CVE-2024-36728

What is CVE-2024-36728?

The TRENDnet TEW-827DRU devices, specifically versions up to and including 2.06B04, are susceptible to a stack-based buffer overflow that occurs within the 'ssi' binary. This vulnerability allows an authenticated user to exploit the system by sending specially crafted POST requests to the 'apply.cgi' endpoint, particularly through the 'action vlan_setting' parameter. By excessively lengthening the inputs for the 'dns1' or 'dns2' keys, an attacker can execute arbitrary code on the device. Such vulnerabilities pose significant risks to network integrity and confidentiality, warranting immediate attention and remediation to secure affected devices.
