How to fix or mitigate CVE-2025-14995?

Within 24 hours, inventory all Tenda FH1201 devices running firmware 1.2.0.14(408) and verify that the web management interface is not exposed to the internet; restrict access to trusted internal networks only. Within 7 days, enforce strong, unique credentials for the management interface, enable logging, and monitor for unusual requests to the /goform/SetIpBind endpoint; if remote management is not required, disable it. Within 30 days, if no vendor patch is released, replace affected devices with supported models or isolate them on a separate VLAN with strict access controls, and monitor the vendor advisory for updates.

Vulnerability Assessment

Weakness	CWE CWE-119 ASVS 5.0 V15 - Secure Coding and Architecture Bounds checking, buffer size validation MITRE ATT&CK 2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	Requires network access to the Tenda FH1201 web management interface running firmware 1.2.0.14(408) and an authenticated low-privilege session (CVSS PR:L) to reach the /goform/SetIpBind endpoint. Exploitation is limited by: (1) authentication to the management panel is needed; (2) the interface is normally LAN-bound, so WAN exploitation depends on remote administration being explicitly enabled (non-default); (3) it is tied to the specific FH1201 firmware build. No user interaction is required once access is obtained.
Impact	This is a stack-based buffer overflow in the /goform/SetIpBind handler of Tenda FH1201 SOHO router firmware, triggered via an unsafe sprintf on the attacker-controlled 'page' argument. The only CVSS data provided is a CVSS 4.0 vector (7.4) scoring AV:N/AC:L/AT:N/PR:L/UI:N with VC/VI/VA:H and E:P (proof-of-concept exploit maturity), indicating a network-reachable but AUTHENTICATED (PR:L) attack with full CIA impact and no scope change. Real-world risk signals are mixed: a public PoC exists (github z472421519/BinaryAudit) confirming reproducibility, but there is NO EPSS score, NO CISA KEV listing, and no evidence of active exploitation - so this is 'publicly available exploit code exists,' not confirmed in-the-wild use. The PR:L requirement is the key limiting factor: exploitation presupposes access to the web management interface (typically a logged-in session on the LAN admin panel), which meaningfully reduces exposure versus a truly unauthenticated flaw. CWE-119 is generic; the description specifies stack-based overflow, so CWE-121 would be more precise. Net: a real but LOW-priority issue driven by low product prevalence and authentication gating, not a widespread emergency.
Exploit ScenarioDerived	An attacker with access to the router's web management interface (LAN-side, or WAN if remote admin is enabled) sends a crafted HTTP request to /goform/SetIpBind with an oversized 'page' parameter. The unbounded sprintf overflows a stack buffer, corrupting the return address to crash the service or execute attacker-supplied code with the router process's privileges. A public proof-of-concept demonstrating the overflow is published on GitHub.

AnalysisAIv1 – Sep 28, 2026

Stack-based buffer overflow in the Tenda FH1201 SOHO router running firmware 1.2.0.14(408) lets an authenticated remote attacker corrupt memory by sending an oversized 'page' parameter to the /goform/SetIpBind endpoint, which is passed unsafely into sprintf. Successful exploitation can yield full loss of confidentiality, integrity, and availability on the device (assessed CVSS 3.1 base 8.8-style impact, vendor/VulDB score 7.4), though the attacker must first reach the web management interface, which is normally LAN-bound, and hold a low-privilege authenticated session (PR:L). Publicly available exploit code exists (a GitHub PoC with reproduction steps), so weaponization is straightforward for anyone who can obtain panel access; there is no CISA KEV listing, so active exploitation is not confirmed from the supplied data.

RemediationAI

No vendor-released patch version is identified in the supplied data - references point only to the general Tenda homepage and VulDB entries, and the PoC repository documents the flaw rather than a fix - so no fixed firmware version can be cited at this time. Until Tenda ships updated firmware, apply compensating controls: disable remote/WAN administration and keep the management interface bound to the LAN only, since exploitation requires reaching the web panel and the interface is normally LAN-restricted (side effect: you lose remote management convenience but remove the primary network exposure vector); replace default administrative credentials and enforce least-privilege accounts to raise the bar beyond the PR:L precondition, though a valid low-privilege session is still sufficient to trigger the overflow so this is only partial; segment the router management VLAN away from untrusted clients and IoT devices (side effect: added network complexity but limits who can reach /goform/SetIpBind); and, if the web UI is not needed, disable or firewall the HTTP management service entirely. Monitor the Tenda support site (https://www.tenda.com.cn/) and the VulDB entry (https://vuldb.com/?id.337689) for a firmware update, and treat the public PoC at https://github.com/z472421519/BinaryAudit/blob/main/PoC/BOF/Tenda_FH1201/SetIpBind/SetIpBind.md as a confirmed attack template when prioritizing these controls.

Technical ContextAI · show details

The affected component is the embedded HTTP management service of the Tenda FH1201, a consumer/SOHO wireless router. The /goform/SetIpBind handler is one of the router's CGI form endpoints, and it copies the user-supplied 'page' argument into a fixed-size stack buffer using sprintf without bounds checking. Because sprintf performs no length validation, a crafted value overflows adjacent stack memory, overwriting saved registers and the return address, which classifies as CWE-119 (improper restriction of operations within the bounds of a memory buffer) manifesting as a classic stack-based buffer overflow (CWE-121). The attack surface is the router's web administration interface; per the CVSS 4.0 vector the vector is network-reachable (AV:N), low complexity (AC:L), requires low privileges (PR:L), and no user interaction (UI:N). Authentication is required (PR:L per both the vendor vector and our independent CVSS 3.1 assessment), so an attacker needs a valid management session before the vulnerable handler can be reached. The CPE cpe:2.3:o:tenda:fh1201_firmware:1.2.0.14\(408\):*:*:*:*:*:*:* pins the exposure to that exact firmware build.

DescriptionCVE.org

A vulnerability has been found in Tenda FH1201 1.2.0.14(408). Affected is the function sprintf of the file /goform/SetIpBind. Such manipulation of the argument page leads to stack-based buffer overflow. The attack may be performed from remote. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

The Tenda FH1201 SOHO router, commonly deployed in branch offices and remote work environments, is affected by a high-severity stack-based buffer overflow (CVE-2025-14995) that can lead to complete device compromise, including loss of confidentiality, integrity, and availability. While exploitation requires an authenticated session on the local management interface, publicly available exploit code exists, lowering the skill barrier for attackers who gain a network foothold. Leadership should care because a compromised router can serve as a pivot point for lateral movement, disrupt business connectivity, and expose sensitive data on the internal network.

Business Impact: High

Compensating Controls

Restrict management interface to trusted LAN, enforce strong authentication, monitor for exploitation attempts, and segment affected devices. No vendor-released patch identified at time of analysis.

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.
