CVE-2022-31526 Explained : Impact and Mitigation

The ThundeRatz/ThunderDocs repository on GitHub is susceptible to a path traversal vulnerability, allowing attackers to access files outside of the intended directory. This CVE was published by MITRE on July 11, 2022.

Understanding CVE-2022-31526

This section will delve into the details of the CVE-2022-31526 vulnerability, its impact, technical aspects, and mitigation strategies.

What is CVE-2022-31526?

The ThundeRatz/ThunderDocs repository on GitHub is impacted by a path traversal vulnerability. This flaw arises from the unsafe use of the Flask send_file function, enabling threat actors to traverse the file system's absolute paths.

The Impact of CVE-2022-31526

Exploitation of this vulnerability could lead to unauthorized access to sensitive files and data stored on the affected system. Attackers can potentially view, modify, or delete critical information, posing a significant risk to the confidentiality and integrity of the repository.

Technical Details of CVE-2022-31526

Let's explore the technical aspects of CVE-2022-31526, including a description of the vulnerability, affected systems, and the exploitation mechanism.

Vulnerability Description

The issue in the ThundeRatz/ThunderDocs repository allows threat actors to perform absolute path traversal, bypassing security mechanisms and accessing unauthorized files and directories.

Affected Systems and Versions

The identified vulnerability affects the ThundeRatz/ThunderDocs repository versions up to 2020-05-01 on GitHub, exposing these outdated versions to exploitation.

Exploitation Mechanism

By leveraging the inadequate handling of file paths in the Flask send_file function, malicious actors can craft requests to traverse the file system beyond the intended directory structure, compromising system integrity.

Mitigation and Prevention
