Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Directly mandates enforcement of approved authorizations for access to system resources like named pipes, addressing the improper access control that bypasses group membership restrictions.

AC-6 Least Privilege partial match

prevent

Employs least privilege to restrict processes like LocalAdminService.exe to minimal necessary access, limiting the impact of privilege escalation even if enforcement fails.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of flaws such as this improper access control vulnerability in LocalAdminService.exe version 1.2.7.23180.

NVD Description

Improper access control in the WCF endpoint in Edgemo (now owned by Danoffice IT) Local Admin Service 1.2.7.23180 on Windows allows a local user to escalate their privileges to local administrator via direct communication with the LocalAdminService.exe named pipe, bypassing…

client-side group membership restrictions.

Deeper analysisAI

CVE-2026-1680, published on 2026-01-30, is an improper access control vulnerability in the WCF endpoint of Edgemo (now owned by Danoffice IT) Local Admin Service version 1.2.7.23180 on Windows. The issue resides in the LocalAdminService.exe named pipe, which fails to enforce client-side group membership restrictions, enabling unauthorized privilege escalation.

A local user with low privileges (PR:L) can exploit this vulnerability with low attack complexity (AC:L) and no user interaction (UI:N) by directly communicating with the named pipe. Successful exploitation allows the attacker to elevate privileges to local administrator, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in the CVSS 3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability is linked to CWE-250 and NVD-CWE-Other.
