Cyber security is crucial for Australian organisations, especially those relying on enterprise Java applications. A newly identified critical file upload vulnerability (CVE-2024-53677) in the Apache Struts2 Framework poses significant risks. This vulnerability could allow path traversal, malicious file uploads, and remote code execution (RCE). Immediate action is required to safeguard your systems and data.
Background: What Has Happened?
A critical vulnerability has been discovered in the Apache Struts2 Framework, a core component of many Java-based enterprise applications. The affected versions include:
- Struts 2.0.0 to Struts 2.3.37 (End of Life)
- Struts 2.5.0 to Struts 2.5.33
- Struts 6.0.0 to Struts 6.3.0.2
Why it matters: Vulnerabilities in Apache Struts2 have been exploited in the past with devastating consequences. High-profile breaches in 2017 and 2023 underscore the risks of unpatched systems. This latest flaw demands immediate attention from organisations using these versions.
Who Is Affected?
This vulnerability impacts Australian organisations that:
- Utilise Java applications built on the Apache Struts2 Framework.
- Develop or support Java applications dependent on this framework.
If your organisation fits these criteria, you could be at risk and should act immediately.
Mitigation: How to Stay Secure
- Assess Your Systems
- Review your environment to identify any use of Apache Struts2.
- Confirm if the version in use is listed as vulnerable.
- Upgrade and Migrate
- Upgrade to Struts 6.4.0 or later.
- Transition to the new Action File Upload Interceptor mechanism for enhanced security.
- Apply Patches
- Implement available patches for all applications utilising Apache Struts2.
