CVE-2023-3765 : What You Need to Know

This article provides detailed information about CVE-2023-3765, focusing on understanding the vulnerability, its impact, technical details, and mitigation strategies for systems affected by Absolute Path Traversal in the GitHub repository mlflow/mlflow prior to version 2.5.0.

Understanding CVE-2023-3765

CVE-2023-3765 addresses the Absolute Path Traversal vulnerability found in the mlflow/mlflow GitHub repository before version 2.5.0. This vulnerability allows an attacker to access files and directories outside the intended directory, potentially leading to unauthorized data disclosure or system compromise.

What is CVE-2023-3765?

The vulnerability CVE-2023-3765 involves Absolute Path Traversal in the mlflow/mlflow repository, enabling a malicious actor to navigate through the file system and access sensitive files or directories that were not meant to be exposed.

The Impact of CVE-2023-3765

Exploiting this vulnerability can have severe consequences, including unauthorized access to confidential data, manipulation of critical files, or complete system compromise. The high severity of this vulnerability (CVSS Base Score 10) categorizes it as critical.

Technical Details of CVE-2023-3765

The following technical aspects provide deeper insights into the CVE-2023-3765 vulnerability:

Vulnerability Description

The Absolute Path Traversal vulnerability in mlflow/mlflow before version 2.5.0 allows attackers to specify absolute file paths, leading to unauthorized access to files and directories outside the intended scope.

Affected Systems and Versions

The affected system is the mlflow/mlflow GitHub repository with versions prior to 2.5.0. Systems using versions earlier than 2.5.0 are susceptible to this Absolute Path Traversal vulnerability.

Exploitation Mechanism

The exploit takes advantage of the lack of proper input validation in the affected versions of mlflow/mlflow, allowing attackers to manipulate file paths and access sensitive information stored on the system.

Mitigation and Prevention

To protect systems from the CVE-2023-3765 vulnerability, the following mitigation and prevention strategies are recommended:

Immediate Steps to Take

Update mlflow/mlflow to version 2.5.0 or newer, which addresses the Absolute Path Traversal vulnerability.
Implement strict input validation mechanisms to prevent malicious actors from manipulating file paths.

Long-Term Security Practices

Regularly monitor and audit file access and permissions to detect any unauthorized activity.
Train developers and system administrators on secure coding practices to prevent similar vulnerabilities in the future.

Patching and Updates

Stay informed about security updates and patches released by mlflow for the mlflow/mlflow repository. Timely patching is crucial to protect systems from known vulnerabilities and security risks.
