A file read/inclusion vulnerability was found in AJP connector in Undertow. This is 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 (RCE).

Mitigation:

Binding Undertow’s AJP port to the loopback interface, or having a firewall which only allows access from trusted hosts would considerably reduce the attack surface to local, or trusted users.
