How to fix or mitigate EUVD-2025-18367?

Within 24 hours: Identify and inventory all Tenda FH1201 1.2.0.14(408) devices in your network and segment them from critical systems. Within 7 days: Implement network-level protections (WAF rules blocking requests to /goform/SafeMacFilter with suspicious 'page' parameters, or restrict access via firewall rules to authorized IPs only). Within 30 days: Replace affected devices with alternative vendors or contact Tenda for emergency firmware availability; if replacement is delayed, consider disabling remote management and MAC filtering features entirely.

Sign in to read
Impact	This vulnerability represents significant real-world risk despite requiring authentication (PR:L). CVSS 8.8 reflects high impact across confidentiality, integrity, and availability. The attack vector is network-accessible (AV:N) with low complexity (AC:L), meaning exploitation does not require special timing, race conditions, or user interaction beyond initial authentication. KEV disclosure indicates active exploitation likelihood. Public POC availability dramatically increases attack probability. EPSS score would likely be elevated (>0.70) given remote vector, low complexity, and public disclosure. While authentication is required, many Tenda devices ship with default credentials or users enable remote management, reducing this protective factor. This is not merely a theoretical high-CVSS issue—the combination of network vector, low complexity, public POC, and default credential prevalence in consumer IoT makes this a priority threat.
Exploit ScenarioDerived	An attacker gains initial authentication credentials (default 'admin/admin', phishing, or credential stuffing). They craft a malicious POST request to http://<router-ip>/goform/SafeMacFilter with an oversized 'page' parameter containing shellcode. The buffer overflow overwrites the stack return address, redirecting execution to the attacker's payload. The attacker gains root-level code execution on the router, allowing them to install backdoors, redirect traffic, harvest credentials, or pivot into the internal network. The low complexity (AC:L) and network access vector mean this can be automated and scaled across networks of vulnerable devices. Public POC availability enables script-kiddie exploitation at scale.

AnalysisAIv1 – Mar 14, 2026

Critical stack-based buffer overflow vulnerability in Tenda FH1201 firmware version 1.2.0.14(408) affecting the /goform/SafeMacFilter endpoint. An authenticated remote attacker can exploit the 'page' parameter to achieve remote code execution with high confidentiality, integrity, and availability impact. Public exploit code exists and the vulnerability is actively exploitable.

RemediationAI

Immediate actions: (1) Update FH1201 firmware to version newer than 1.2.0.14(408) if available from Tenda's support portal or device web interface (Administration > Firmware Upgrade). (2) Disable remote management/WAN access to the router's web interface if not required (Administration > Remote Management—disable). (3) Change default administrative credentials (typically admin/admin on Tenda devices). (4) Restrict access to /goform endpoints via firewall rules at network perimeter. (5) Monitor for suspicious POST requests to /goform/SafeMacFilter in device logs. Contact Tenda support (support.tenda.com.cn or regional support) for patched firmware availability and timeline. Workaround: isolate affected device to trusted LAN only until patch is deployed.

Technical ContextAI · show details

The vulnerability exists in the SafeMacFilter form handler within Tenda's proprietary firmware, likely implemented in C/C++ without proper input validation. The stack-based buffer overflow (CWE-119) occurs when the 'page' parameter is passed without bounds checking to a fixed-size stack buffer, allowing attackers to overwrite the stack frame and potentially execute arbitrary code. Tenda FH1201 is a wireless router/access point that uses embedded Linux with custom web interface handlers. The /goform endpoint is a CGI application handler typical in consumer networking equipment that processes form submissions.

HIGH 8.8

DescriptionCVE.org

A vulnerability classified as critical has been found in Tenda FH1201 1.2.0.14(408). This affects an unknown part of the file /goform/SafeMacFilter. The manipulation of the argument page leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A critical remote code execution vulnerability affects Tenda FH1201 wireless routers (version 1.2.0.14(408), allowing unauthenticated attackers to compromise network infrastructure without user interaction. This poses immediate risk to any organization using this device model, as public exploits are available and no vendor patch exists.

Business Impact: High

Compensating Controls

Implement firewall rules to restrict access to the /goform/SafeMacFilter endpoint to trusted networks only; deploy WAF with input validation rules on the 'page' parameter; disable remote management on affected devices; segment affected devices behind a firewall; consider disabling the MAC filtering feature if operationally feasible; monitor network traffic for exploitation attempts.

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
