GHSA-3G84-HPR9-W7V5

Vulnerability from github – Published: 2026-07-14 03:31 – Updated: 2026-07-20 18:32

Details

SAProuter on Microsoft Windows allows an unauthenticated attacker to load library (DLL) files from an untrusted location, allowing them to execute malicious code on the system. This could enable the attacker to hijack the DLL loading process and achieve arbitrary code execution. This has high impact on confidentiality, integrity and availability of the system.

Severity

8.4 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
