Publication date: 2026-02-27

Last updated on: 2026-03-10

Assigner: VulnCheck

Description
openDCIM version 23.04, through commit 4467e9c4, contains a missing authorization vulnerability in install.php and container-install.php. The installer and upgrade handler expose LDAP configuration functionality without enforcing application role checks. Any authenticated user can access this functionality regardless of assigned privileges. In deployments where REMOTE_USER is set without authentication enforcement, the endpoint may be accessible without credentials. This allows unauthorized modification of application configuration.

Executive Summary

This vulnerability exists in openDCIM version 23.04 up to commit 4467e9c4 and involves missing authorization checks in the install.php and container-install.php files.

Specifically, the installer and upgrade handler expose LDAP configuration functionality without enforcing application role checks, meaning any authenticated user can access and modify this functionality regardless of their assigned privileges.

In some deployments where REMOTE_USER is set without proper authentication enforcement, this endpoint may even be accessible without credentials, allowing unauthorized users to modify application configuration.

Impact Analysis

This vulnerability can allow unauthorized users to modify critical application configurations related to LDAP settings.

Such unauthorized modifications can lead to security breaches, including unauthorized access, privilege escalation, or disruption of authentication mechanisms.

In environments where REMOTE_USER is set without authentication enforcement, attackers might exploit this vulnerability without needing any credentials.
