can be launched remotely. The exploit is now 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

SI-10 Information Input Validation good match
prevent

Directly enforces validation of the GroupName argument in the /goform/formFireWall management interface to prevent buffer overflow from malicious input.

SI-16 Memory Protection good match
prevent

Implements memory protections like stack canaries, ASLR, and DEP to mitigate exploitation of the strcpy buffer overflow vulnerability.

SI-2 Flaw Remediation good match
prevent

Mandates timely flaw remediation for vulnerabilities like CVE-2026-2086, including patching or workarounds despite lack of vendor response.

Security SummaryAI

CVE-2026-2086 is a buffer overflow vulnerability in the UTT HiPER 810G device, affecting versions up to 1.7.7-171114. The flaw exists in the strcpy function of the /goform/formFireWall file within the Management Interface component, triggered by manipulation of the GroupName argument.

The vulnerability enables remote exploitation by attackers with low privileges (PR:L), as indicated by its CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Successful attacks can result in high impacts to confidentiality, integrity, and availability, with a public exploit available for use.

Advisories referenced in GitHub issues (alc9700jmo/CVE/issues/22) and VulDB entries (ctiid.344653, id.344653) detail the issue but note that the vendor was contacted early without response. No patches or specific mitigations are mentioned.
