AI-Generated

The vulnerability affects the Zabbix Agent installed on Windows systems in custom directories lacking secure access permissions. An attacker could exploit this by placing a malicious DLL in these directories, enabling DLL sideloading and potentially compromising the application. Organizations using Zabbix Agent on Windows should prioritize addressing this issue to mitigate the risk of unauthorized access and ensure secure installation practices.

Original NVD Description

When Zabbix Agent was installed on Windows into a custom installation directory, the installer did not verify whether the selected directory had secure access permissions. If the target directory allowed unauthorized users to modify its contents, an attacker could place a malicious DLL that could later be loaded by the application, resulting in DLL sideloading. The installer has been hardened to detect potentially unsafe installation directories and now requires explicit user confirmation before proceeding with installation in such locations. This reduces the risk of accidental installation into directories with inappropriate permissions while preserving compatibility with existing deployment scenarios.
