Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents buffer overflow by validating the manipulated 'page' argument in the fromSetIpBind function before processing.
Requires timely identification, reporting, and patching of the specific buffer overflow flaw in Tenda F453 firmware version 1.0.0.3.
Implements memory safeguards such as stack canaries or non-executable memory to block unauthorized code execution from the buffer overflow exploitation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in internet-facing router web form (/goform/SetIpBind) directly enables remote code execution via T1190 (Exploit Public-Facing Application).

Deeper analysisAI
CVE-2026-3379 is a buffer overflow vulnerability in the Tenda F453 router firmware version 1.0.0.3. The flaw affects the fromSetIpBind function within the /goform/SetIpBind file, where manipulation of the "page" argument triggers the overflow. Published on 2026-03-01, it is associated with CWE-119 and CWE-120.
The vulnerability enables remote exploitation by attackers with low privileges. Per its CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), it requires network access and low privileges but low attack complexity and no user interaction, allowing high impacts on confidentiality, integrity, and availability.
