CVE-2022-39367 : Vulnerability Insights and Analysis

A vulnerability has been identified in the handling of uploaded QTI ZIP files in QTIWorks, a software suite for standards-based assessment delivery. The vulnerability, assigned as CVE-2022-39367, impacts versions prior to 1.0-beta15 of QTIWorks Engine.

Understanding CVE-2022-39367

This section will delve into the details of CVE-2022-39367, discussing the vulnerability, its impact, technical details, and mitigation strategies.

What is CVE-2022-39367?

CVE-2022-39367 is a security flaw that allows users to upload QTI content packages as ZIP files. The ZIP handling code fails to adequately validate file paths within ZIP files, potentially leading to the insertion of files into unauthorized locations within the filesystem.

The Impact of CVE-2022-39367

In extreme cases, this vulnerability could permit anonymous users to manipulate files in arbitrary locations on the filesystem. However, the default configuration of QTIWorks Engine mitigates the risk to some extent by restricting ZIP file uploads to users with 'instructor' privileges.

Technical Details of CVE-2022-39367

Let's explore the technical aspects of CVE-2022-39367, including the vulnerability description, affected systems, and the exploitation mechanism.

Vulnerability Description
