Short explanation
In NEC WebSAM WinShare versions 7.5.0 and earlier (excluding 7.3.3), 7.6.0 and 7.7.0‑7.7.1, improper access control on the program installation folder allows a low‑privileged local user to execute arbitrary code with SYSTEM privileges via a crafted DLL file.
Code execution with SYSTEM privileges can give an attacker full control over the affected host.
What should be done?
- Restrict write permissions on the installation folder
- Monitor for suspicious DLLs in the directory
- Follow vendor security advisories and patches
- Employ application whitelisting
- Upgrade to a version where the issue is fixed when available
