CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-25674 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Tenda Ac10 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 36th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
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-2025-25674 is a buffer overflow vulnerability (CWE-120) in the Tenda AC10 V1.0 router running firmware version V15.03.06.23. The flaw occurs in the form_fast_setting_wifi_set function when processing the 'ssid' parameter, earning a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Published on 2025-02-20, it exposes the device to potential remote exploitation due to inadequate bounds checking on user-supplied input.
A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, likely enabling arbitrary code execution, device takeover, or denial of service.
The primary reference at https://github.com/jangfan/my-vuln/blob/main/Tenda/AC10V1/fast_setting_wifi_set.md details the vulnerability, including the affected endpoint and parameter. No official vendor patches or mitigation advisories are specified in available data.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and analysis can find missing size checks before deployment.
Input validation directly enforces size checks before buffer copies.
Engineering principles require bounds checking and safe buffer handling in design.
Memory protection limits the impact of an overflow once it occurs.

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.
Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.
Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.
Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.
Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
