The handle_request function in lib/HTTPServer.pm in Monitorix before 3.3.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the URI.

3.4.0 - 02-Dec-2013 ====================

  - Added a complete statistical Memcached graph. [#27]

    - Added support for different BIND stats versions (2 and       3 right now). (thanks to Ivo Brhel, ivb AT volny.cz)

  - Added two new alerts in the 'disk' graph in order to     know if a disk drive has exceeded or reached a threshold     for reallocated and pending sectors. (suggested by     Matthew Connelly, maff AT maff.im)

  - Added a new option called 'max_historic_years' (with a     default value of 1), which enables the ability to have     up to 5 years of data. Beware with this option because     it generates a new '.rrd' file every time the value is     extended, losing the current historical data. (suggested     by Mohan Reddy, Mohan.Reddy AT analog.com)

  - Improved the regexp when collecting data from devices's     interrupts which also fixes some annoying messages on     using non-numeric arguments.

  - Added support for the Pure-FTPd logs in the 'serv' and     'ftp' graphs.

    - Added the new configuration option 'https_url'. [#31]

    - Fixed error messages about use of uninitialized values       in 'system' graph on BSD systems.

  - Fixed error messages about not numeric argument in     addition in 'fs' graph on BSD systems.

  - Fixed in 'emailreports' to use the command line     'hostname' if the variable $ENV{HOSTNAME} is not defined     (Debian/Ubuntu and perhaps other systems). (thanks to     Skibbi, skibbi AT gmail.com for pointing this out)

  - Fixed the error message 'String ends after the = sign on     CDEF:allvalues=' in the 'int' graph (the Interrupts     graph is pending to have a complete rewrite).

  - Fixed the 'int' graph in order to be more compatible     with Raspberry Pi.

    - Fixed in 'bind.pm' to store a 0 value if threads are       disabled. [#29]

    - Fixed to correctly sent images in graphs 'proc',       'port' and 'fail2ban' when using emailreports. (thanks       to Benoit Segond von Banchet, bjm.segondvonbanchet AT       telfort.nl for pointing this out)

  - Fixed to show the real hostname in the emailreports.

    - Fixed the 'int' graph in order to be compatible with       Excito B3 product. (thanks to Patrick Fallberg,       patrick AT fallberg.net for pointing this out)

  - Fixed to correctly sanitize the input string in the     built-in HTTP server which led into a number of security     vulnerabilities. [#30]

  - Fixed the lack of minimum definition in some data     sources of 'bind' graph. (thanks to Andreas Itzchak     Rehberg, izzy AT qumran.org for pointing this out)

  - Fixed a fail to adequately sanitize request strings of     malicious JavaScript. [#30] (thanks to Jacob Amey, jamey     AT securityinspection.com for pointing this out)

  - Fixed a typo in monitorix.service. [#32]

    - Fixed the requests value in the 'nginx' graph. Now it       honours the label to show the value per second,       instead of per minute. (thanks to Martin Culak, culak       AT firma.azet.sk for pointing this out)

  - Small fixes and typos.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Monitorix built-in HTTP server does not properly sanitize HTTP GET request strings, allowing for remote, arbitrary command execution via a specially crafted HTTP request.
