Summary

CVE-2025-10169 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 1200Gw 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 7% 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.

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

CVE-2025-10169 is a buffer overflow vulnerability (CWE-119, CWE-120) in UTT 1200GW routers running firmware up to version 3.0.0-170831. The flaw affects an unknown functionality within the /goform/ConfigWirelessBase CGI endpoint, where manipulation of the 'ssid' argument triggers the buffer overflow condition.

The vulnerability enables remote exploitation by attackers possessing low privileges (PR:L), with low attack complexity (AC:L) and no requirement for user interaction (UI:N). Successful exploitation can result in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in its CVSS v3.1 base score of 8.8. A public exploit is available, increasing the risk of active attacks.

VulDB advisories and a GitHub repository document the issue, including details on the endpoint and proof-of-concept exploit. The vendor was contacted early regarding disclosure but provided no response, and no patches or mitigations are available from official sources.

The exploit's public availability indicates it could be readily exploited in the wild against unpatched UTT 1200GW devices.
