Gestionnaire Libre de Parc Informatique (GLPI) is an open-source software package that aids organizations in managing their IT resources. IT departments rely on GLPI for its comprehensive features, such as ITIL Service Desk, license tracking, and software auditing capabilities. However, a vulnerability was recently discovered in this popular software, affecting versions up to 10..3, that allows malicious users to create public RSS feeds targeted at injecting harmful code into the dashboards of unsuspecting victims. Thankfully, this issue has now been resolved with the release of GLPI version 10..4.

In this long read post, we will explore the details of this vulnerability, CVE-2022-39375, the risks associated with it, how attackers could potentially exploit it, and what you can do to protect your GLPI environment.

Vulnerability Description

CVE-2022-39375 is an executable code deployment risk that permits attackers to alter the content of public RSS feeds by injecting malicious code. As a result, all users with access to the shared dashboard are exposed to the harmful code without knowing it.

This vulnerability exists in GLPI versions up to and including 10..3. The software developers have released a patch, so upgrading to version 10..4 or later is strongly recommended.

Exploit Details

To exploit this vulnerability, an attacker would need to create a public RSS feed on the GLPI platform. Subsequently, malicious code would be injected into the content of this feed. When other users add or access the tampered RSS feed to their dashboards, their environments become compromised, allowing a potential attacker to gain unauthorized privileges, steal sensitive data, or disrupt the system operations.

Here's an example of how an attacker could insert harmful code into an RSS feed with a malicious code snippet:
