CVE-2023-34106 in GLPI
Summary
by MITRE • 07/05/2023
GLPI is a free asset and IT management software package. Versions of the software starting with 0.68 and prior to 10.0.8 have an incorrect rights check on a on a file accessible by an authenticated user. This allows access to the list of all users and their personal information. Users should upgrade to version 10.0.8 to receive a patch.

The vulnerability identified as CVE-2023-34106 affects GLPI, a widely-used open-source asset and IT management software package that organizations rely on for maintaining comprehensive inventory and user management systems. This security flaw exists in versions ranging from 0.68 through 10.0.7, creating a significant access control weakness that undermines the software's security posture. The issue stems from an improper rights check implementation within the application's permission system, specifically affecting a file that should be restricted to authorized users only but remains accessible to any authenticated user within the system.
The technical flaw represents a classic authorization bypass vulnerability that falls under CWE-285, which addresses improper authorization within software applications. The vulnerability allows authenticated users to access sensitive data through a file that contains comprehensive user information including personal details and system access credentials. This represents a critical breach in the principle of least privilege, where users can access data beyond their intended scope of authorization. The flaw essentially creates a backdoor within the application's permission model, enabling unauthorized data exposure through legitimate user accounts that should not have access to such sensitive information.
The operational impact of this vulnerability extends beyond simple data exposure, as it compromises the integrity of the entire user management system within GLPI environments. Organizations using affected versions face potential risks including identity theft, unauthorized access to system resources, and violation of privacy regulations such as GDPR or HIPAA depending on the nature of the stored information. The vulnerability affects the confidentiality aspect of the CIA triad, as it allows unauthorized disclosure of user personal information and system access details. Attackers could leverage this weakness to gain insights into organizational user structures, potentially enabling more sophisticated attacks such as targeted phishing campaigns or privilege escalation attempts.
Security practitioners should prioritize immediate remediation by upgrading to GLPI version 10.0.8, which contains the necessary patch addressing the rights check implementation. The fix addresses the root cause by implementing proper access controls that ensure only authorized administrative users can access the sensitive user information file. Organizations should also conduct thorough security assessments of their GLPI installations to identify any potential exploitation attempts and review access logs for suspicious activities. Additionally, implementing network segmentation and monitoring for unusual data access patterns can provide additional layers of defense. The vulnerability demonstrates the importance of regular security updates and proper access control implementation, as outlined in the mitre attack framework's defense in depth principles. Organizations should also consider implementing automated patch management systems to ensure timely deployment of security fixes across their IT infrastructure.
