CVE-2022-36112 : Vulnerability Insights and Analysis

A detailed overview of the Blind Server-Side Request Forgery (SSRF) vulnerability affecting GLPI software.

Understanding CVE-2022-36112

In this section, we will delve into what CVE-2022-36112 entails.

What is CVE-2022-36112?

The vulnerability identified as CVE-2022-36112 exposes GLPI to Blind Server-Side Request Forgery (SSRF) attacks. GLPI, which stands for Gestionnaire Libre de Parc Informatique, is an IT Management Software package that integrates ITIL Service Desk features and software auditing. The SSRF exploit in GLPI allows malicious actors to utilize server-side requests for scanning server ports and services on the GLPI server or its private network. Notably, the exploit operates in a 'blind' manner, where query responses are not directly visible to end-users. It is recommended that users upgrade to GLPI version 10.0.3 to address this security concern.

The Impact of CVE-2022-36112

The Common Vulnerability Scoring System (CVSS) v3.1 base score for CVE-2022-36112 is rated as 3.5, categorizing it as having a low severity level. The attack complexity is high, with an attack vector of network. While the confidentiality impact is low and there is no integrity impact, the exploit necessitates low privileges required for execution. The exploit causes a change in scope and does not require any user interaction. Despite its severity rating, the vulnerability does not have an availability impact.
