AI-Generated

Konga versions prior to 2.1.0 are vulnerable to a privilege escalation flaw that allows low-privileged local attackers on Windows to execute arbitrary code by placing malicious OpenSSL configuration or library files in a writable directory. This vulnerability can be exploited to elevate privileges to that of the user or service account running Konga, potentially leading to unauthorized access or control over the system. Organizations using Konga, particularly on Windows, should prioritize patching to mitigate this high-severity risk.

Original NVD Description

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.
