Impact Analysis

This vulnerability can impact you by allowing remote attackers to fully compromise the affected Tenda WH450 router without any authentication. Exploiting the stack-based buffer overflow can lead to arbitrary code execution, denial of service (DoS), and compromise of the device's confidentiality, integrity, and availability. There are no known mitigations, so the affected device is at high risk. [2, 3]

Executive Summary

CVE-2025-15006 is a critical stack-based buffer overflow vulnerability in the Tenda WH450 router version 1.0.0.18. It exists in the HTTP Request Handler component at the /goform/CheckTools endpoint. The vulnerability is caused by improper handling of the 'ipaddress' argument, which allows a remote attacker to trigger a stack-based buffer overflow without authentication. This overflow can lead to arbitrary code execution or denial of service on the device. A proof-of-concept exploit is publicly available. [2, 3]

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests to the /goform/CheckTools endpoint on Tenda WH450 routers for unusually long or malformed 'ipaddress' parameters that could trigger a stack-based buffer overflow. A practical detection method is to capture and analyze network traffic for such suspicious requests. For example, using tcpdump or Wireshark to filter HTTP requests to /goform/CheckTools and inspect the 'ipaddress' parameter length. A sample tcpdump command to capture relevant traffic could be: tcpdump -i <interface> -A 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' | grep '/goform/CheckTools'. Additionally, custom scripts or intrusion detection systems (IDS) rules can be created to alert on HTTP requests with abnormally long 'ipaddress' parameters targeting this endpoint. [2, 3]

Mitigation Strategies

Immediate mitigation steps include replacing the affected Tenda WH450 router (version 1.0.0.18) with a non-vulnerable device, as no known countermeasures or patches currently exist. Additionally, restricting remote access to the router's HTTP management interface, implementing network-level filtering to block suspicious requests to /goform/CheckTools, and monitoring for exploit attempts can help reduce risk. Since the exploit is publicly available and can be triggered remotely without authentication, isolating the device from untrusted networks or disabling the vulnerable service if possible are recommended interim measures.
