Summary
Konga before 2.1.0 has a privilege escalation vulnerability allowing low-privileged local attackers to execute arbitrary code by planting OpenSSL config or library files in a hardcoded filesystem path absent from default installations. On Windows, the missing directory is writable by any authenticated user, enabling attackers to create it and place malicious files that execute with the privileges of the launching account.
Risk Assessment
A local attacker could gain elevated privileges and take control of the system, potentially leading to full compromise.
Recommendation
Update Konga to version 2.1.0 or later and restrict local access. Ensure system directories are properly secured.

Original NVD description (English source)
Konga before 2.1.0 contains a privilege escalation vulnerability that allows low-privileged local attackers to execute arbitrary code by planting attacker-controlled OpenSSL configuration or library files in a hardcoded filesystem path absent from default installations. On Windows, the missing directory resides in a location writable by any authenticated local user, enabling attackers to create the directory and place malicious files that execute at the privilege level of the user or service account that launches Konga, facilitating privilege escalation.
