CVE-2025-41659 PUBLISHED CVSS 8.300000190734863 HIGH

A vulnerability in the runtime system allows low-privileged remote attackers to access the PKI folder via CODESYS protocol, enabling them to read and write certificates and keys. This exposes sensitive cryptographic data and allows unauthorized certificates to be trusted. However, all services remain available, only certificate based encryption and signing features are concerned. The issue affects systems using the optional CmpOpenSSL component for cryptographic operations.
