This article provides details about CVE-2023-22974, including its description, impact, technical details, and mitigation strategies.

Understanding CVE-2023-22974

CVE-2023-22974 is a Path Traversal vulnerability found in setup.php in OpenEMR version less than 7.0.0. This vulnerability enables remote unauthenticated users to access arbitrary files by manipulating a connection to a MySQL server controlled by an attacker.

What is CVE-2023-22974?

The CVE-2023-22974 vulnerability in OpenEMR < 7.0.0 allows unauthorized users to read sensitive files on the server by exploiting a path traversal issue in the setup.php file. This can lead to unauthorized access to critical data stored within the OpenEMR system.

The Impact of CVE-2023-22974

The impact of CVE-2023-22974 can be significant as it compromises the confidentiality of data stored within the OpenEMR system. Attackers can leverage this vulnerability to extract sensitive information, potentially resulting in data breaches and privacy violations.

Technical Details of CVE-2023-22974

The technical details of CVE-2023-22974 include the vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The vulnerability resides in the setup.php file of OpenEMR < 7.0.0 and arises due to inadequate input validation, allowing remote attackers to traverse the file system and read files they should not have access to.
