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.
