Summary

CVE-2025-7795 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Fh451 Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4.7% 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).

Deeper analysis

A stack-based buffer overflow vulnerability exists in Tenda FH451 firmware version 1.0.0.9. The issue is located in the fromP2pListFilter function of the /goform/P2pListFilter endpoint, where improper handling of the page argument allows an attacker to overwrite the stack. The flaw is tracked under CWE-119 and CWE-121 and carries a CVSS 4.0 score of 7.4.

The vulnerability can be triggered remotely by an authenticated user without user interaction. Successful exploitation grants the attacker full control over the affected device, resulting in high impact to confidentiality, integrity, and availability. Public proof-of-concept code has already been published, confirming that the issue is exploitable in its current form.

The EPSS score has remained flat at 0.1816 with no material increase since disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly prevents the stack-based buffer overflow by requiring validation of the untrusted 'page' argument in the /goform/P2pListFilter endpoint.

prevent

Implements memory protection mechanisms such as stack canaries or DEP to block exploitation of the stack-based buffer overflow in the fromP2pListFilter function.

prevent

Requires timely remediation of the known buffer overflow flaw in Tenda FH451 firmware version 1.0.0.9 via patching to eliminate the vulnerability.
