AI description

Automated description summarized from trusted sources.

CVE-2025-27237 describes a vulnerability found in Zabbix Agent and Agent 2 when running on Windows operating systems. The flaw arises because the OpenSSL configuration file, which is used by these agents, is loaded from a directory that can be written to by users with low privileges. This insecure file permission allows a malicious actor with local access to modify the OpenSSL configuration. By injecting a Dynamic Link Library (DLL) into this configuration, an attacker can achieve local privilege escalation.

Description: In Zabbix Agent and Agent 2 on Windows, the OpenSSL configuration file is loaded from a path writable by low-privileged users, allowing malicious modification and potential local privilege escalation by injecting a DLL.
