A critical path traversal vulnerability has been discovered in Apache OFBiz, an open-source Enterprise Resource Planning (ERP) system widely used by businesses across the globe. This vulnerability, assigned the identifier CVE-2024-32113, affects all versions of Apache OFBiz before 18.12.13. If left unpatched, this security flaw can result in unauthorized access and manipulation of sensitive files and documents.

This blog post will provide an in-depth analysis of the CVE-2024-32113 vulnerability, including code snippets, links to original references, and exploit details. Read along to learn how this vulnerability impacts Apache OFBiz and what actions you can take to mitigate the risk.

Vulnerability Details

The CVE-2024-32113 vulnerability arises due to the improper limitation of a pathname to a restricted directory, commonly known as 'Path Traversal.' This vulnerability enables an attacker to access and manipulate files and directories outside the intended restricted directory.

In the case of Apache OFBiz, the application fails to properly validate user-supplied input, leading to a path traversal vulnerability. An attacker can potentially gain unauthorized access to sensitive files and directories, leading to severe consequences such as data leakage, manipulation, or denial-of-service.

Exploit Details

To exploit the CVE-2024-32113 vulnerability, an attacker can craft a malicious URL or input a malicious input into vulnerable fields containing directory traversal payloads such as "../" or "..\". By doing so, the attacker can break out of the restricted directory and access files outside the intended folder. The following is a simplified code snippet to demonstrate the vulnerability:

private String getFilePath(HttpServletRequest request) {
    String path = request.getParameter("path");
    if (path != null && !path.isEmpty()) {
        return "/UsersDirectory/" + path;
    }
    return "/UsersDirectory/default";
}

In this code snippet, the 'getFilePath' function takes a user-supplied 'path' parameter from an HTTP request and concatenates it to the "/UsersDirectory/" string. When an attacker provides a malicious input, such as "../etc/passwd", the function returns a path outside the intended directory, leading to a path traversal vulnerability.

Mitigations and Recommendations

To address the CVE-2024-32113 vulnerability, Apache has released a security patch in the latest version of OFBiz (18.12.13). Users are highly recommended to upgrade their OFBiz installations promptly to avoid security risks.

Upgrade Apache OFBiz to version 18.12.13

Download the latest OFBiz version from the official website here: https://ofbiz.apache.org/download.html

Furthermore, developers should take additional measures to prevent path traversal vulnerabilities in their applications:

Use built-in functions or libraries to handle file and directory paths securely.

3. Employ least-privilege access controls, ensuring users and applications have the minimal permissions necessary to perform required tasks.

Conclusion

CVE-2024-32113, a path traversal vulnerability in Apache OFBiz, poses a serious threat to organizations utilizing this software. It is essential to act quickly and apply the appropriate security patches to mitigate the risk. Stay up-to-date on the latest security vulnerabilities, and ensure that your organization remains secure in an ever-changing threat landscape.
