CVE-2022-31187 in GLPI
Summary
by MITRE • 09/14/2022
GLPI stands for Gestionnaire Libre de Parc Informatique and is a Free Asset and IT Management Software package, that provides ITIL Service Desk features, licenses tracking and software auditing. Affected versions were found to not properly neutralize HTML tags in the global search context. Users are advised to upgrade to version 10.0.3 to resolve this issue. Users unable to upgrade should disable global search.

CVE-2022-31187 represents a cross-site scripting vulnerability within the GLPI asset and IT management platform that arises from inadequate input sanitization in the global search functionality. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically manifesting as a stored XSS flaw where HTML tags are not properly neutralized during search operations. The affected versions of GLPI fail to implement proper output encoding or sanitization mechanisms when processing user input within the global search context, creating a persistent security weakness that allows attackers to inject malicious scripts into the application's search results.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious HTML content within search parameters that gets stored and subsequently executed when other users view the search results. This creates a dangerous environment where authenticated users can be subjected to script execution attacks, potentially leading to session hijacking, credential theft, or redirection to malicious websites. The vulnerability exists because GLPI's global search functionality does not adequately filter or escape HTML characters before rendering search results, allowing attackers to inject JavaScript payloads that execute in the context of other users' browsers.
The operational impact of this vulnerability extends beyond simple script execution as it compromises the integrity of the entire IT management platform. Attackers could leverage this weakness to escalate privileges, access sensitive asset information, or manipulate software auditing data that forms the foundation of IT governance processes. The vulnerability particularly affects organizations relying on GLPI for critical ITIL service desk operations, as it undermines the trust model of the application and potentially exposes the entire IT infrastructure to unauthorized access. Security teams face increased risk of persistent threats where attackers can maintain footholds within the system through compromised search functionality.
Organizations should prioritize immediate remediation by upgrading to GLPI version 10.0.3, which implements proper HTML sanitization measures and input validation. For environments where immediate upgrades are not feasible, administrators should disable the global search functionality entirely to mitigate the risk. Additional defensive measures include implementing web application firewalls to detect and block suspicious search parameters, conducting regular security assessments of search-related functionality, and establishing monitoring procedures for anomalous search queries that may indicate exploitation attempts. The vulnerability demonstrates the critical importance of input validation in web applications and aligns with ATT&CK technique T1213.002 for Credential Access through data manipulation, as it provides a potential pathway for unauthorized access to system resources through session manipulation and credential exposure.
