Understanding CVE-2023-32322

This section provides insights into the impact, technical details, and mitigation strategies related to CVE-2023-32322.

What is CVE-2023-32322?

Ombi, an open-source media request application, prior to version 4.38.2, is vulnerable to an arbitrary file read exploit. This vulnerability allows Ombi administrative users to access files not intended for their access on the host operating system.

The Impact of CVE-2023-32322

The arbitrary file read vulnerability in Ombi poses a significant risk as it can lead to unauthorized access to sensitive files on the host machine. Attackers exploiting this vulnerability can potentially compromise user data and system integrity.

Technical Details of CVE-2023-32322

A deeper dive into the vulnerability specifics, affected systems, and exploitation mechanisms.

Vulnerability Description

The flaw originates from unsanitized input parameters in the

ReadLogFile

and

Download

endpoints in

SystemControllers.cs

. Attackers can manipulate the

logFileName

parameter to traverse directories and access unauthorized files on the system.

Affected Systems and Versions

The vulnerability affects versions of the Ombi application prior to version 4.38.2, exposing systems to potential exploitation.

Exploitation Mechanism

By exploiting the unfiltered

logFileName

parameter in the

SystemControllers.cs

, attackers can navigate to files outside the intended directory using traversal techniques, leading to unauthorized data disclosure.

Mitigation and Prevention

Guidelines on how to mitigate the CVE-2023-32322 vulnerability and prevent potential security risks.

Immediate Steps to Take

Users are strongly advised to upgrade the Ombi application to version 4.38.2 or later to remediate the arbitrary file read vulnerability. Implementing the latest patches is critical to enhancing system security.
