Summary

CVE-2025-15232 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-2025-15232 is a stack-based buffer overflow vulnerability in the Tenda M3 router firmware version 1.0.0.13(4903). The flaw affects the formSetAdPushInfo function in the /goform/setAdPushInfo file, where manipulation of the mac or terminal arguments triggers the overflow. Published on 2025-12-30, it is rated 8.8 on the CVSS 3.1 scale (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow).

The vulnerability enables remote exploitation by authenticated users with low privileges. Attackers can send crafted requests to the affected endpoint, leading to potential arbitrary code execution with high impacts on confidentiality, integrity, and availability. A public exploit is available, increasing the risk of widespread abuse.

VulDB advisories (ctiid.338628, id.338628, submit.725494) document the issue, with a detailed proof-of-concept on GitHub at dwBruijn/CVEs/blob/main/Tenda/setAdPushInfo.md. No specific patches or mitigations are detailed in the references; security practitioners should check the Tenda website (tenda.com.cn) for firmware updates and consider network segmentation or disabling the endpoint where possible.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can discover stack-buffer overflows before deployment.

Input validation directly stops untrusted data from exceeding stack buffer bounds.

Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.

Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.
