"The EventLog Analyzer version installed on the remote web server is
affected by multiple information disclosure vulnerabilities :

  - A flaw exists in the 'agentHandler' servlet that allows
    a remote attacker to retrieve user names and password
    hashes and other sensitive information. (CVE-2014-6038)

  - A flaw exists in the 'hostdetails' servlet that allows a
    remote attacker to retrieve user names and passwords for
    systems managed by EventLog Analyzer. (CVE-2014-6039)

Note that Nessus only checked for the flaw outlined by CVE-2014-6038;
however, it is highly likely that the version is also affected by the
flaw outlined in CVE-2014-6039.");
