| A vulnerability has been discovered in Apache Struts 2, which could allow for remote code execution. Apache Struts 2 is an open-source web application framework for developing Java EE web applications. Successful exploitation could allow for remote code execution in the context of underlying operating system. Depending on the privileges associated with the logged on user, an attacker could then install programs; view, change, or delete data. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. |
| Threat Intelligence There are currently no reports of this vulnerability being exploited in the wild. |
| Systems Affected |
| Struts 2.0.0 – Struts 2.3.37 (EOL) Struts 2.5.0 – Struts 2.5.32 Struts 6.0.0 – Struts 6.3.0 |
| Risk Government: – Large and medium government entities: High – Small government entities: Medium |
| Businesses: – Large and medium business entities: High – Small business entities: Medium |
| Home Users: Low |
| Technical Summary A vulnerability has been discovered in Apache Struts 2, which could allow for remote code execution. |
| Recommendations |
| Apply appropriate updates provided by Apache to vulnerable systems immediately after appropriate testing. Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them. Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems. Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. |
