More information:

Markus Krell discovered that Xymon (formerly known as Hobbit), 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-2016-2058

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

For Debian 7 Wheezy, these problems have been fixed in version 4.3.0~beta2.dfsg-9.1+deb7u1.

We recommend that you upgrade your xymon packages.
