Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Arbitrary File Upload. A file inclusion vulnerability was found in the AJP connector enabled with a default AJP configuration port of 8009. A remote, unauthenticated attacker could exploit this vulnerability to read web application files from a vulnerable server. In instances where the vulnerable server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types and trigger this vulnerability to gain remote code execution.
