Summary

CVE-2025-7544 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ac1206 Firmware. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 26% 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-7544 is a stack-based buffer overflow vulnerability affecting the Tenda AC1206 wireless router running firmware version 15.03.06.23. The issue exists in the formSetMacFilterCfg function of the /goform/setMacFilterCfg endpoint and is triggered by unsanitized input to the deviceList argument, resulting in memory corruption tracked under CWE-119 and CWE-121.

An authenticated remote attacker can supply a crafted deviceList value to overflow the stack, potentially leading to arbitrary code execution or a crash that disrupts device operation. The CVSS 4.0 score of 7.4 reflects network attack vector, low complexity, and high impact on confidentiality, integrity, and availability with no user interaction required.

Public references include a detailed proof-of-concept on GitHub and corresponding entries on Vuldb, confirming the flaw has been disclosed but providing no official vendor patch or mitigation guidance. The associated EPSS score has remained flat at 0.0170 with no material rise since publication.

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.
