Published: 14 July 2025
Summary
CVE-2025-7570 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
Directly prevents buffer overflows by requiring validation and sanitization of inputs like the remoteSrcTemp argument in the vulnerable /goform/aspRemoteApConfTempSend endpoint.
Implements memory protection mechanisms such as stack canaries, ASLR, and DEP to mitigate exploitation of buffer overflows even if invalid input reaches the vulnerable functionality.
Requires timely remediation of identified flaws like CVE-2025-7570 through patching, configuration changes, or feature disablement to eliminate the buffer overflow vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in public web form (/goform/aspRemoteApConfTempSend) of network device directly enables remote exploitation for code execution (T1190).
NVD Description
A vulnerability was found in UTT HiPER 840G up to 3.1.1-190328. It has been rated as critical. Affected by this issue is some unknown functionality of the file /goform/aspRemoteApConfTempSend. The manipulation of the argument remoteSrcTemp leads to buffer overflow. The…

attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Deeper analysisAI
CVE-2025-7570 is a critical buffer overflow vulnerability (CVSS 3.1 score of 8.8, vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) in UTT HiPER 840G routers up to version 3.1.1-190328. The flaw affects an unknown functionality within the /goform/aspRemoteApConfTempSend file, where manipulation of the remoteSrcTemp argument triggers the overflow, classified under CWE-119 and CWE-120.
An attacker with low privileges can exploit this remotely with low attack complexity and no user interaction required. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially leading to arbitrary code execution or system takeover.
References from VulDB and a GitHub repository indicate that a proof-of-concept exploit has been publicly disclosed and may be used. The vendor was contacted early regarding the issue but provided no response, and no patches or specific mitigations are mentioned in the available advisories.
