Executive brief
openDCIM, an open-source tool for managing data center infrastructure like server racks and network connections, contains a critical security flaw. An attacker can inject malicious commands into the system's configuration, allowing them to take full control of the web server. This could lead to the theft of sensitive data center layouts, service disruptions, or a complete compromise of the host system.
Technical details
An OS command injection vulnerability exists in openDCIM version 23.04 (up to commit 4467e9c4) within the report_network_map.php component. The application retrieves the 'dot' configuration value from the fac_Config database table and passes it directly to the PHP exec() function without validation or sanitization. While this requires the ability to modify database configurations, researchers have demonstrated that this can be achieved by chaining this bug with a separate SQL injection vulnerability in install.php. In many Docker-based deployments where authentication is misconfigured or absent, this chain allows unauthenticated remote attackers to execute arbitrary shell commands in the context of the web server process. A patch has been submitted in pull request #1664.
