Published: 13 July 2025
Summary
CVE-2025-7549 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Fh1201 Firmware. Its CVSS base score is 8.8 (High).
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
Remediating the identified stack-based buffer overflow flaw in frmL7ProtForm directly eliminates the vulnerability to manipulation of the 'page' argument.
Validating information inputs to the /goform/L7Prot endpoint ensures the 'page' argument does not exceed buffer bounds, preventing the overflow.
Memory protection mechanisms like stack canaries and non-executable memory prevent exploitation of the stack-based buffer overflow for arbitrary code execution.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The stack-based buffer overflow in the router's web interface (/goform/L7Prot) is remotely exploitable via a crafted 'page' parameter, enabling arbitrary code execution consistent with exploitation of a public-facing application.
NVD Description
A vulnerability was found in Tenda FH1201 1.2.0.14(408) and classified as critical. This issue affects the function frmL7ProtForm of the file /goform/L7Prot. The manipulation of the argument page leads to stack-based buffer overflow. The attack may be initiated remotely. The…

Deeper analysisAI
CVE-2025-7549 is a critical stack-based buffer overflow vulnerability in the Tenda FH1201 router firmware version 1.2.0.14(408). The flaw resides in the frmL7ProtForm function within the /goform/L7Prot file, triggered by manipulation of the "page" argument. It is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow), earning a CVSS v3.1 base score of 8.8.
An attacker with low privileges can exploit this vulnerability remotely over the network with low attack complexity and no user interaction. Exploitation involves sending a crafted request to the vulnerable endpoint, potentially resulting in high impacts to confidentiality, integrity, and availability, such as arbitrary code execution or denial of service.
VulDB advisories and GitHub references document the issue, including a publicly disclosed proof-of-concept exploit at https://github.com/panda666-888/vuls/blob/main/tenda/fh1201/frmL7ProtForm.md#poc, which heightens the urgency for affected users to isolate devices or pursue vendor updates if available. No specific patches are detailed in the provided references.
