Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mitigates the CVE by requiring timely remediation of the known buffer overflow flaw in Tenda CH22 firmware via patches or updates.

prevent

Prevents exploitation by enforcing validation and bounds checking on the manipulable 'page' argument in the /goform/P2pListFilter endpoint.

prevent

Mitigates buffer overflow impacts through memory protection mechanisms like stack canaries, ASLR, and DEP, hindering arbitrary code execution.

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?

Buffer overflow in web endpoint (/goform/P2pListFilter) enables remote exploitation of public-facing application for arbitrary code execution.

Deeper analysisAI

CVE-2025-12274 is a buffer overflow vulnerability affecting Tenda CH22 firmware version 1.0.0.1. The issue resides in the fromP2pListFilter function within the /goform/P2pListFilter file, where manipulation of the "page" argument triggers the overflow. Associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input), 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), indicating high severity due to its potential for significant impact.

An attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L) and without requiring user interaction (UI:N). Successful exploitation allows high confidentiality, integrity, and availability impacts (C:H/I:H/A:H) within the unchanged scope (S:U), potentially enabling arbitrary code execution or denial of service on the affected device.

Advisories and details are available via VulDB entries (ctiid.329946, id.329946, submit.674165) and a GitHub issue at QIU-DIE/CVE/issues/23, with the vendor site at tenda.com.cn listed as a reference. The exploit has been publicly disclosed and may be used, though no specific patch or mitigation steps are detailed in the available information.
