CVE-2023-48710 in iTop
Summary
by MITRE • 04/15/2024
iTop is an IT service management platform. Files from the `env-production` folder can be retrieved even though they should have restricted access. Hopefully, there is no sensitive files stored in that folder natively, but there could be from a third-party module. The `pages/exec.php` script as been fixed to limit execution of PHP files only. Other file types won't be retrieved and exposed. The vulnerability is fixed in 2.7.10, 3.0.4, 3.1.1, and 3.2.0.

The vulnerability identified as CVE-2023-48710 affects iTop, an IT service management platform that serves as a centralized system for managing IT services and infrastructure. This security flaw represents a critical access control issue that allows unauthorized retrieval of files from the env-production folder, which should normally be restricted to prevent exposure of sensitive configuration data and system artifacts. The vulnerability stems from inadequate file access controls within the platform's file retrieval mechanisms, specifically impacting the pages/exec.php script that handles file execution and retrieval operations.
The technical flaw manifests in the platform's failure to properly validate file access requests, enabling attackers to bypass intended restrictions and access files that should remain protected within the env-production directory structure. This directory typically contains environment-specific configuration files, database connection parameters, and other system artifacts that could provide valuable information to threat actors. The vulnerability is particularly concerning because it allows for arbitrary file retrieval rather than just limited access to specific file types, creating potential exposure of sensitive system information that could be leveraged for further attacks.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates opportunities for attackers to gather intelligence about the system's configuration and potentially identify weaknesses in the platform's security posture. Even if the native installation does not contain sensitive files, third-party modules or custom configurations could introduce vulnerable data that would be accessible through this flaw. The exposure of configuration files could reveal database credentials, API keys, or other sensitive information that could be used to compromise the entire IT service management infrastructure.
The remediation implemented in versions 2.7.10, 3.0.4, 3.1.1, and 3.2.0 addresses the core issue by restricting the pages/exec.php script to execute PHP files only, thereby preventing access to other file types that could contain sensitive information. This fix aligns with security best practices for access control and file handling, ensuring that only intended executable files are processed through the platform's file retrieval mechanisms. The vulnerability classification aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, and represents a significant improvement in the platform's security posture. Organizations using iTop should prioritize upgrading to the patched versions to mitigate the risk of unauthorized file access and protect their IT service management infrastructure from potential exploitation. The fix demonstrates the importance of proper input validation and access control enforcement in preventing information disclosure vulnerabilities that could compromise system security.
