Description Timothy Walsh 2016-09-15 23:49:31 EDT

A long URL when sent to EAP 7 Server operating as a reverse proxy with default buffer sizes causes a DoS.

A long URL (about 1900 characters) is sent, the proxy server

    return error 500 (that's ok)
    starts to consume 100% CPU
    starts to fill logs log file with exceptions very fast (so disk space gets exhausted quickly)
    E.g. some infinite loop is initiated by the request. Proxy server must be restarted to stop the problem.
