CVE-2023-41888 in GLPI
Summary
by MITRE • 10/25/2023
GLPI stands for Gestionnaire Libre de Parc Informatique is a Free Asset and IT Management Software package, that provides ITIL Service Desk features, licenses tracking and software auditing. The lack of path filtering on the GLPI URL may allow an attacker to transmit a malicious URL of login page that can be used to attempt a phishing attack on user credentials. Users are advised to upgrade to version 10.0.10. There are no known workarounds for this vulnerability.

The CVE-2023-41888 vulnerability affects GLPI, a widely used open-source IT asset and service management platform that serves organizations in maintaining their IT infrastructure and providing ITIL service desk capabilities. This vulnerability stems from insufficient input validation within the application's URL handling mechanism, specifically concerning path parameters that are not properly filtered or sanitized. The flaw exists in the authentication flow where the application fails to adequately validate or sanitize the redirect URL parameter, creating a potential vector for malicious actors to manipulate the login page redirection behavior.
This security weakness allows attackers to craft malicious URLs that appear to originate from legitimate GLPI instances, enabling them to conduct sophisticated phishing campaigns targeting user credentials. The vulnerability specifically impacts the login page functionality where users are redirected to potentially harmful sites after authentication attempts. The lack of proper path filtering means that attackers can inject arbitrary URLs that bypass normal security checks, making it particularly dangerous as users may be unaware they are being redirected to fraudulent sites designed to capture their credentials. This issue represents a classic case of insecure redirection that can be exploited to deceive users into providing sensitive information to malicious actors.
The operational impact of this vulnerability extends beyond simple credential theft, as it undermines the fundamental trust model of the GLPI application and its users. Organizations relying on GLPI for asset management and service desk operations face significant risks including unauthorized access to their IT infrastructure data, potential privilege escalation, and exposure of sensitive organizational information. The vulnerability affects the authentication security boundary of the application, potentially allowing attackers to gain unauthorized access to systems that should be protected by proper authentication mechanisms. This weakness can be particularly devastating in enterprise environments where GLPI is used for managing critical IT assets and service requests, as successful exploitation could lead to complete compromise of the IT management infrastructure.
Security practitioners should note that this vulnerability aligns with CWE-601 which specifically addresses URL redirection and forwarding vulnerabilities, and it maps to ATT&CK technique T1566 which covers phishing attacks through various delivery methods. The recommended mitigation strategy involves immediate upgrading to GLPI version 10.0.10, as no effective workarounds exist for this particular flaw. Organizations should conduct thorough security assessments of their GLPI deployments to identify potential exploitation attempts and implement monitoring for suspicious URL patterns in authentication logs. Network administrators should also consider implementing web application firewalls and URL filtering mechanisms to provide additional protection layers against malicious redirection attempts. The vulnerability highlights the critical importance of proper input validation and secure redirection practices in web applications, particularly those handling sensitive authentication flows.
