JBoss sysadmins need to get busy hardening their systems, with a rising number of attacks against the system, according to Imperva.
The attacks are based on an exploit that was published back in October by Andrea Micalizzi. The exploit code gave remote attackers arbitrary code execution access to HP's PCM Plus and Application Lifecycle Management systems without authentication.
The attack also works against McAfee, Symantec and IBM products using JBoss 4.x and 5.x.
Imperva's advisory states that the compay is now seeing an increasing amount of attack traffic using the exploit.
What's surprising, Imperva says, is that while the Micalizzi exploit code only hit the waiting world this year, the vulnerability has been known since 2011. The attack works by exploiting the HTTP invoker service in JBoss, used to provide access to Enterprise Java Beans.
Imperva says the Micalizzi exploit “abuses invoker/EJBInvokerServlet to deploy a web shell code that enables the hacker to execute arbitrary Operating System commands on the victim sever’s system.” In the HP environment, this would provide access to the PCM Plus and ALM management consoles.
There are currently 23,000 servers exposing their JBoss management interfaces to the Internet, up from 7,000 in 2011, Imperva says, with infections spotted in the wild.
In October, HP updated its JBoss implementation here. ®
