Apache Struts is a popular framework for creating Java web applications. It provides developers with a wide range of tools to simplify the development process and build more secure and reliable applications. The Struts 1 plugin is a component of Apache Struts that allows developers to integrate legacy Struts 1 applications with new Struts 2 applications. This plugin provides backwards compatibility for older applications, allowing developers to take advantage of the new features and security enhancements in Struts 2 while still maintaining their existing applications.
The CVE-2017-9791 vulnerability is a serious security flaw in the Struts 1 plugin for Apache Struts. This vulnerability can be exploited by an attacker to execute arbitrary code on a target system by passing a malicious field value to the ActionMessage. This can be accomplished through a variety of methods, including sending a specially crafted request to a vulnerable application, or by injecting malicious code into a legitimate request.
If this vulnerability is exploited, it can lead to a wide range of consequences for the target system. Attackers may be able to access sensitive data, execute arbitrary code, or even take control of the system entirely. This can result in data breaches, system downtime, and other serious security issues.
