CVE-2022-31544 : Exploit Details and Defense Strategies

This article discusses the CVE-2022-31544 vulnerability found in the meerstein/rbtm repository on GitHub, allowing absolute path traversal due to the unsafe use of the Flask send_file function.

Understanding CVE-2022-31544

This section covers the details, impact, technical aspects, and mitigation strategies related to the CVE-2022-31544 vulnerability.

What is CVE-2022-31544?

The CVE-2022-31544 vulnerability exists in the meerstein/rbtm repository up to version 1.5 on GitHub, enabling attackers to perform absolute path traversal by exploiting the unsafe utilization of the Flask send_file function.

The Impact of CVE-2022-31544

This vulnerability could allow malicious actors to traverse absolute paths, potentially leading to unauthorized access to sensitive files and directories within the affected systems.

Technical Details of CVE-2022-31544

In this section, we will delve deeper into the vulnerability's description, affected systems, versions, and exploitation mechanisms.

Vulnerability Description

The flaw in the meerstein/rbtm repository stems from the insecure implementation of the Flask send_file function, opening avenues for threat actors to traverse absolute paths.

Affected Systems and Versions

All versions of the meerstein/rbtm repository up to version 1.5 are impacted by CVE-2022-31544, exposing them to the risk of absolute path traversal attacks.

Exploitation Mechanism

By exploiting the Flask send_file function's unsafe usage, attackers can manipulate file paths to unauthorizedly access files and directories on the target system.

Mitigation and Prevention

This section provides guidance on immediate steps to take, long-term security practices, and the significance of applying patches and updates.

Immediate Steps to Take

System administrators should apply security best practices, verify and sanitize file paths, and restrict access to sensitive directories to mitigate the risk of exploitation.
