CVE-2025-11652
Published: 13 October 2025
Summary
CVE-2025-11652 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 518G Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 42.3% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly validates the txtMin2 argument in /goform/formTaskEdit_ap processing to prevent buffer overflow exploitation from malformed remote inputs.
Implements memory protections such as stack canaries, ASLR, and DEP to block arbitrary code execution from buffer overflow exploits.
Requires timely identification, reporting, and remediation of the buffer overflow flaw, including patching or system replacement despite vendor non-response.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in public-facing web management interface (/goform/) enables remote exploitation for arbitrary code execution, directly mapping to T1190: Exploit Public-Facing Application.
NVD Description
A vulnerability was found in UTT 进取 518G up to V3v3.2.7-210919-161313. This issue affects some unknown processing of the file /goform/formTaskEdit_ap. The manipulation of the argument txtMin2 results in buffer overflow. The attack may be performed from remote. The exploit…

Deeper analysisAI
CVE-2025-11652 is a buffer overflow vulnerability (CWE-119, CWE-120) affecting UTT 进取 518G devices up to version V3v3.2.7-210919-161313. The flaw occurs in some unknown processing of the /goform/formTaskEdit_ap file, where manipulation of the txtMin2 argument triggers the overflow.
The vulnerability can be exploited remotely by an attacker requiring low privileges (PR:L), with network access, low attack complexity, and no user interaction. It has 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), allowing high impacts to confidentiality, integrity, and availability, potentially enabling arbitrary code execution or denial of service.
Advisories from VulDB and related sources note that a proof-of-concept exploit is publicly available on GitHub. The vendor was contacted early for disclosure but provided no response, and no patches or official mitigations are referenced. The exploit could be used in practice given its public status.
