Denial Of Service
The remote host is running a version of the JanaServer which is vulnerable to various denial of service vulnerabilities. An attacker may exploit these vulnerabilities by sending a malformed request to the remote service and cause it to enter an infinite loop, thus refusing connections and using 100% of the CPU of the remote host.
Upgrade to JanaServer 2.4.5 or newer.
