performed from remote. The exploit has been released to the public and may be used for attacks.

Mitigating Controls (NIST 800-53 r5)AI

preventrecover

Directly remediates the stack-based buffer overflow by applying firmware patches or updates from the vendor to eliminate the flaw in the HTTP Request Handler.

prevent

Enforces validation of the 'GO' argument in the /goform/wirelessRestart endpoint to prevent improper restriction of operations within memory bounds leading to buffer overflow.

prevent

Implements memory protection mechanisms such as stack canaries, ASLR, and DEP to detect and prevent exploitation of the stack-based buffer overflow.

Security SummaryAI

CVE-2025-14878 is a stack-based buffer overflow vulnerability affecting the Tenda WH450 router on firmware version 1.0.0.18. The issue impacts an unknown function in the /goform/wirelessRestart file within the HTTP Request Handler component, where manipulation of the "GO" argument triggers the overflow. Published on 2025-12-18, it is associated with CWEs-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow) and carries a CVSS v3.1 base score of 9.8.

The vulnerability enables remote exploitation with no authentication, privileges, or user interaction required (AV:N/AC:L/PR:N/UI:N). Attackers can achieve high impacts across confidentiality, integrity, and availability (C:H/I:H/A:H), potentially leading to arbitrary code execution on the affected device.

A proof-of-concept exploit has been publicly released on GitHub (https://github.com/z472421519/BinaryAudit/blob/main/PoC/BOF/Tenda_WH450/wirelessRestart/wirelessRestart.md), with further details available via VulDB (https://vuldb.com/?ctiid.337369, https://vuldb.com/?id.337369, https://vuldb.com/?submit.715357). The vendor site is at https://www.tenda.com.cn/, though no specific patch or mitigation guidance is detailed in the references.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Stack-based buffer overflow in the public-facing HTTP request handler (/goform/wirelessRestart) of Tenda WH450 router enables remote, unauthenticated arbitrary code execution or DoS via exploitation of a public-facing application.
