CVE-2026-28517: openDCIM <= 23.04 OS Command Injection via dot Configuration Parameter

openDCIM version 23.04, through commit 4467e9c4, contains an OS command injection vulnerability in report_network_map.php. The application retrieves the 'dot' configuration parameter from the database and passes it directly to exec() without validation or sanitization. If an attacker can modify the fac_Config.dot value, arbitrary commands may be executed in the context of the web server process.

Security readout for executives and security teams

Plain-English summary

openDCIM can be made to run operating-system commands if an attacker can change its stored Graphviz dot setting. That turns a configuration value into code execution under the web server account. The impact is critical for exposed or weakly controlled openDCIM deployments, but the supplied evidence does not prove active exploitation in the wild.

Executive priority

Prioritize this for immediate assessment because successful exploitation can lead to full server-side command execution. Focus first on internet-facing openDCIM, systems with shared admin access, and environments where openDCIM has access to sensitive infrastructure data.

Technical view

CVE-2026-28517 is CWE-78 in openDCIM 23.04 through commit 4467e9c4. report_network_map.php reads fac_Config.dot and passes it to exec() without validation or sanitization. Public references include exploit-tagged material and a project pull request, but the bundle does not identify a fixed release or KEV listing.

Likely exposure

Primary exposure is openDCIM deployments where an unauthenticated or low-control path can modify fac_Config.dot, including through another vulnerability or database write access. Internet-facing openDCIM instances and systems with broad admin access are higher risk.

Exploitation context

The CVE is not listed as KEV in the bundle. Public exploit-tagged references exist, including a technical writeup and repository, so defenders should treat details as publicly available. Do not assume confirmed active exploitation without additional evidence.

Researcher notes

The key condition is control over fac_Config.dot. The CVSS vector says network, low complexity, no privileges, and no user interaction, but the supplied description frames exploitation around modifying a stored configuration value. Validate the reachable write path before concluding practical unauthenticated exploitability.

Mitigation direction

  • Review openDCIM PR 1664 and vendor guidance for an official fix.
  • Upgrade or patch once a vendor-confirmed fixed version is available.
  • Restrict access to openDCIM administration and configuration-changing functions.
  • Limit database write privileges affecting fac_Config.dot.
  • Run the web server with least privilege and monitor command execution.
  • Block public access if openDCIM is not intended to be internet-facing.

Validation and detection

  • Inventory openDCIM deployments and confirm version or commit level.
  • Check whether report_network_map.php passes the dot setting to exec().
  • Review fac_Config.dot for unexpected or unsafe values.
  • Audit who can modify configuration values or write to the database.
  • Review logs for network map report access after configuration changes.
