CVE-2025-7571
Published: 14 July 2025
Summary
CVE-2025-7571 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Utt 840G 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 18.8% 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
Validates the Username input to the /goform/aspApBasicConfigUrcp endpoint to prevent buffer overflows from oversized or malformed data.
Deploys memory protections such as stack canaries, ASLR, and DEP to block exploitation of the buffer overflow even if triggered.
Requires timely identification, reporting, and remediation of the known buffer overflow flaw in UTT HiPER 840G firmware.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in web form (/goform/aspApBasicConfigUrcp) enables remote code execution against a network device's public-facing administrative interface.
NVD Description
A vulnerability classified as critical has been found in UTT HiPER 840G up to 3.1.1-190328. This affects an unknown part of the file /goform/aspApBasicConfigUrcp. The manipulation of the argument Username leads to buffer overflow. It is possible to initiate the…

Deeper analysisAI
CVE-2025-7571 is a critical buffer overflow vulnerability (CWE-119, CWE-120) in UTT HiPER 840G routers up to version 3.1.1-190328. The flaw affects an unknown component of the /goform/aspApBasicConfigUrcp file, where manipulation of the Username argument triggers the overflow. Published on 2025-07-14, it carries 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).
An attacker with low privileges can exploit this vulnerability remotely with low complexity and no user interaction required. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially leading to arbitrary code execution on the affected device.
Advisories and references, including VulDB entries and GitHub proof-of-concept code, confirm public disclosure of an exploit. The vendor was contacted early regarding the issue but provided no response, and no patches or specific mitigations are detailed in the available information.
