"Markus Krell discovered that xymon, a network- and
applications-monitoring system, was vulnerable to the following
security issues :

  - CVE-2016-2054
    The incorrect handling of user-supplied input in the
    'config' command can trigger a stack-based buffer
    overflow, resulting in denial of service (via
    application crash) or remote code execution.

  - CVE-2016-2055
    The incorrect handling of user-supplied input in the
    'config' command can lead to an information leak by
    serving sensitive configuration files to a remote user.

  - CVE-2016-2056
    The commands handling password management do not
    properly validate user-supplied input, and are thus
    vulnerable to shell command injection by a remote user.

  - CVE-2016-2057
    Incorrect permissions on an internal queuing system
    allow a user with a local account on the xymon master
    server to bypass all network-based access control lists,
    and thus inject messages directly into xymon.

  - CVE-2016-2058
    Incorrect escaping of user-supplied input in status
    webpages can be used to trigger reflected cross-site
    scripting attacks."
