CVE-2025-41659: Codesys Control For Beaglebone Sl

High severity, CVSS 8.3. EPSS: 0.2% chance of exploitation in the next 30 days.

A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all services remain available, only unencrypted communication is possible if the certificates are deleted.
