CVE-2026-2070
Published: 06 February 2026
Description
A vulnerability has been found in UTT 进取 520W 1.7.7-180627. The affected element is the function strcpy of the file /goform/formPolicyRouteConf. Such manipulation of the argument GroupName leads to buffer overflow. The attack can be executed 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.
Mitigating Controls (NIST 800-53 r5)AI
Requires validation of the GroupName input parameter to prevent buffer overflows triggered by oversized or malformed data in the strcpy function.
Implements memory protections such as non-executable stacks and address space randomization to mitigate successful exploitation of the buffer overflow for arbitrary code execution.
Mandates timely remediation of identified flaws like this publicly disclosed buffer overflow through patching, workarounds, or system isolation.
Security SummaryAI
CVE-2026-2070 is a buffer overflow vulnerability in the UTT 进取 520W router running firmware version 1.7.7-180627. The issue resides in the strcpy function within the /goform/formPolicyRouteConf file, where improper handling of the GroupName argument allows overflow conditions. This flaw, classified under CWE-119 and CWE-120, was published on 2026-02-06 and 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), indicating high severity due to its potential for significant impact.
The vulnerability can be exploited remotely by an authenticated attacker with low privileges (PR:L) over the network with low complexity and no user interaction required. Successful exploitation of the buffer overflow could grant high confidentiality, integrity, and availability impacts, potentially enabling arbitrary code execution, data manipulation, or denial of service on the affected device.
Advisories referenced in sources such as VulDB (ctiid.344637, id.344637, submit.745264) and a GitHub repository detail the vulnerability and note that an exploit has been publicly disclosed and may be in use. The vendor was contacted early regarding the issue but provided no response, and no patches or mitigations are mentioned in the available information.

MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in router's web management interface (/goform/formPolicyRouteConf) enables remote exploitation of a public-facing application (T1190) by authenticated low-privilege users, facilitating arbitrary code execution consistent with exploitation for privilege escalation (T1068).
