Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 18.4% of CVEs by exploit likelihood; 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 stack-based buffer overflow by requiring validation of the deviceList argument for length, format, and bounds before processing in the formSetWifiMacFilterCfg function.
Mitigates exploitation of the stack-based buffer overflow through memory protections like stack canaries, ASLR, and non-executable stacks on the affected router firmware.
Ensures flaws like the CVE-2025-7598 buffer overflow are identified, prioritized, and remediated via firmware updates to eliminate the vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Stack-based buffer overflow in public web form endpoint (/goform/setWifiFilterCfg) on network device directly enables remote exploitation of a public-facing application by authenticated users, matching T1190.
NVD Description
A vulnerability classified as critical was found in Tenda AX1803 1.0.0.1. Affected by this vulnerability is the function formSetWifiMacFilterCfg of the file /goform/setWifiFilterCfg. The manipulation of the argument deviceList leads to stack-based buffer overflow. The attack can be launched remotely.…

Deeper analysisAI
CVE-2025-7598 is a critical stack-based buffer overflow vulnerability (CWE-119, CWE-121) affecting Tenda AX1803 routers on firmware version 1.0.0.1. The flaw exists in the formSetWifiMacFilterCfg function within the /goform/setWifiFilterCfg file, where manipulation of the deviceList argument triggers the overflow. Published on 2025-07-14, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
The vulnerability enables remote exploitation by authenticated users with low privileges. Attackers can send crafted requests to the affected endpoint, leading to a buffer overflow that compromises the device's confidentiality, integrity, and availability with high impact. A proof-of-concept exploit has been publicly disclosed.
