CVE-2024-51995 in iTop
Summary
by MITRE • 11/07/2024
Combodo iTop is a web based IT Service Management tool. An attacker can request any `route` we want as long as we specify an `operation` that is allowed. This issue has been addressed in version 3.2.0 by applying the same access control pattern as in `UI.php` to the `ajax.render.php` page which does not allow arbitrary `routes` to be dispatched. All users are advised to upgrade. There are no known workarounds for this vulnerability.

The vulnerability identified as CVE-2024-51995 affects Combodo iTop, a web-based IT Service Management platform that serves as a comprehensive solution for organizations managing their IT infrastructure and service delivery. This security flaw represents a critical access control bypass issue that allows unauthorized users to execute arbitrary operations within the application's routing system. The vulnerability stems from insufficient validation of route parameters in the application's ajax rendering functionality, specifically in the ajax.render.php component.
The technical implementation of this vulnerability exploits a pattern where the application accepts user-supplied route parameters without proper authorization checks. An attacker can leverage this weakness by crafting malicious requests that specify any desired route while ensuring the operation parameter aligns with allowed operations within the system. This creates a scenario where the application's access control mechanisms are circumvented, allowing execution of operations that should otherwise be restricted to authorized users. The flaw specifically impacts the ajax.render.php page which serves as a critical interface for dynamic content rendering in the iTop application.
From an operational perspective, this vulnerability presents a significant risk to organizations using Combodo iTop as their primary IT service management solution. Attackers could potentially escalate privileges, access restricted functionality, or manipulate system behavior through unauthorized route execution. The impact extends beyond simple information disclosure to potentially enabling full system compromise if the vulnerable routes provide access to critical administrative functions. Organizations relying on iTop for their IT service management operations face potential exposure to data breaches, service disruption, and unauthorized system modifications.
The vulnerability has been addressed in version 3.2.0 through implementation of enhanced access control patterns that mirror the security measures already present in UI.php. This remediation approach ensures that the ajax.render.php page enforces the same strict route validation and authorization checks as other critical application components. The fix aligns with security best practices by implementing principle of least privilege and defense in depth strategies. Organizations should prioritize upgrading to version 3.2.0 or later to mitigate this risk, as no effective workarounds exist for this particular vulnerability. This security patch demonstrates the importance of consistent access control implementation across all application interfaces and highlights the potential consequences of incomplete security controls in web-based enterprise applications. The vulnerability classification aligns with CWE-285 (Improper Authorization) and may map to ATT&CK techniques involving privilege escalation and unauthorized access to system resources.
