CVE-2025-15231 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda M3 Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 48th 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-15231 is a stack-based buffer overflow vulnerability affecting the Tenda M3 router on firmware version 1.0.0.13(4903). The flaw exists in the formSetRemoteVlanInfo function within the /goform/setVlanInfo file, where manipulation of the ID, vlan, or port arguments triggers the overflow. Associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow), 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 over the network with low complexity and no user interaction, but requires low privileges such as basic authentication. An attacker could achieve high impacts across confidentiality, integrity, and availability, potentially leading to arbitrary code execution on the affected device through the buffer overflow.
Advisories and further details are documented on VulDB (ctiid.338627, id.338627, submit.725493), with a public exploit disclosure available on GitHub at dwBruijn/CVEs/blob/main/Tenda/setRemoteVlanInfo.md. The Tenda manufacturer website (tenda.com.cn) provides general product information, though specific patch guidance is not detailed in the referenced sources.
The exploit has been publicly disclosed and may be utilized, increasing the risk of real-world attacks against unpatched Tenda M3 devices.
