There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Munin before 2.999.6 has a local file write vulnerability when CGI graphs are enabled. Setting multiple
    upper_limit GET parameters allows overwriting any file accessible to the www-data user. (CVE-2017-6188)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3215-1 advisory.

    It was discovered that Munin incorrectly handled CGI graphs. A remote attacker could use this issue to     overwrite arbitrary files as the www-data user.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for munin fixes the following issues :

  - An attacker has been able to write arbitrary local files     with the permissions of the web server, by using     parameter injection (boo#1026539, CVE-2017-6188)

  - The MySQL plugin has been fixed to work correctly     against MySQL 5.5 on Leap 42.1

- CVE-2017-6188: Upstream PR 797: Fix wrong parameter     expansion in CGI

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

Stevie Trujillo discovered a local file write vulnerability in munin, a network-wide graphing framework, when CGI graphs are enabled. GET parameters are not properly handled, allowing to inject options into munin-cgi-graph and overwriting any file accessible by the user running the cgi-process.

The remote host is affected by the vulnerability described in GLSA-201710-05 (Munin: Arbitrary file write)

    When Munin is compiled with CGI graphics enabled then the files       accessible to the www-data user can be overwritten.
  Impact :

    A local attacker, by setting multiple upper_limit GET parameters, could       overwrite files accessible to the www-user.
  Workaround :

    There is no known workaround at this time.

Munin before 2.999.6 has a local file write vulnerability when CGI graphs are enabled. Setting multiple upper_limit GET parameters allows overwriting any file accessible to the www-data user. (CVE-2017-6188)
