EXPLOIT

openDCIM version 23.04, through commit 4467e9c4, contains a SQL injection vulnerability in Config::UpdateParameter. The install.php and container-install.php handlers pass user-supplied input directly into SQL statements using string interpolation without prepared statements or proper input sanitation. An authenticated user can execute arbitrary SQL statements against the underlying database.

command SQL injection via LDAP configuration form to overwrite Graphviz dot binary path in fac_Config↗

• → Monitor HTTP POST/GET requests to install.php and container-install.php on openDCIM deployments; these endpoints should not be accessible post-installation and any traffic to them is suspicious. ↗
• → The exploit chain requires exactly five HTTP requests to achieve RCE and spawn a reverse shell; correlate sequences of rapid requests across install.php and report_network_map.php from the same source IP. ↗
• → Flag modifications to the fac_Config table's Graphviz dot binary path column in the openDCIM database, as the exploit overwrites this value to achieve command injection. ↗

• · The SQL injection vulnerability is exploitable by authenticated users in standard deployments; however, in Docker deployments where REMOTE_USER is set without authentication enforcement, install.php may be reachable without credentials. ↗
• · The vulnerability affects openDCIM version 23.04 through commit 4467e9c4; the Metasploit module confirms the range extends through version 25.01 on Ubuntu with Apache. ↗
• · Full RCE via the exploit chain depends on the presence of the Graphviz dot binary path being configurable in fac_Config and report_network_map.php being accessible; the exploit restores the original config after payload delivery. ↗
