CVE-2023-51441 Explained : Impact and Mitigation

This article provides insights into CVE-2023-51441, a vulnerability impacting Apache Axis 1.x, leading to SSRF potential and the necessary mitigation steps.

Understanding CVE-2023-51441

In this section, we will delve into the specifics of CVE-2023-51441 to understand its impact and implications.

What is CVE-2023-51441?

CVE-2023-51441 is an Improper Input Validation vulnerability in Apache Axis that enables users with access to the admin service to potentially execute SSRF attacks. This vulnerability affects Apache Axis through version 1.3. It is important to note that Axis 1.x has reached its End of Life (EOL), and users are advised to transition to alternative SOAP engines, such as Apache Axis 2/Java, for enhanced security.

The Impact of CVE-2023-51441

The vulnerability in Apache Axis 1.x poses a significant risk as it allows malicious actors to exploit SSRF when untrusted input is submitted to the service admin HTTP API. This can lead to unauthorized access, data leakage, or further compromise of the system.

Technical Details of CVE-2023-51441

In this section, we will explore the technical aspects of CVE-2023-51441, including the vulnerability description, affected systems, and the exploitation mechanism.

Vulnerability Description
