A flaw was found in WebSAM Winshare due to improper access control permissions on its installation folder. A locally authenticated attacker with low privileges can exploit this vulnerability by placing a crafted Dynamic Link Library (DLL) file into the program directory. When a high-privileged system process loads this file, the attacker can achieve arbitrary code execution with elevated SYSTEM privileges.

Description OSIDB Bzimport 2026-11-09 04:21:19 UTC
Improper Access Control in the program installation folder in NEC Corporation WebSAM Winshare Ver 7.5.0 and earlier (excluding Ver 7.3.3), Ver 7.6.0 and Ver 7.7.0 through 7.7.1 on Windows allows a locally authenticated low-privileged attacker to execute arbitrary code with SYSTEM privileges via a crafted DLL file that is loaded by a SYSTEM-level process.
