Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities have been discovered in ruby-actionpack-3.2, a web-flow and rendering framework and part of Rails :

CVE-2015-7576

A flaw was found in the way the Action Controller component compared user names and passwords when performing HTTP basic authentication. Time taken to compare strings could differ depending on input, possibly allowing a remote attacker to determine valid user names and passwords using a timing attack.

CVE-2016-0751

A flaw was found in the way the Action Pack component performed MIME type lookups. Since queries were cached in a global cache of MIME types, an attacker could use this flaw to grow the cache indefinitely, potentially resulting in a denial of service.

CVE-2016-0752

A directory traversal flaw was found in the way the Action View component searched for templates for rendering. If an application passed untrusted input to the 'render' method, a remote, unauthenticated attacker could use this flaw to render unexpected files and, possibly, execute arbitrary code.

CVE-2016-2097

Crafted requests to Action View might result in rendering files from arbitrary locations, including files beyond the application's view directory. This vulnerability is the result of an incomplete fix of CVE-2016-0752. This bug was found by Jyoti Singh and Tobias Kraze from Makandra.

CVE-2016-2098

If a web applications does not properly sanitize user inputs, an attacker might control the arguments of the render method in a controller or a view, resulting in the possibility of executing arbitrary ruby code. This bug was found by Tobias Kraze from Makandra and joernchen of Phenoelit.

CVE-2016-6316

Andrew Carpenter of Critical Juncture discovered a cross-site scripting vulnerability affecting Action View. Text declared as 'HTML safe' will not have quotes escaped when used as attribute values in tag helpers.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.6-6+deb7u3.

We recommend that you upgrade your ruby-actionpack-3.2 packages.

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

Solution

Upgrade the affected ruby-actionpack-3.2 package.

How to Run

Here is how to run the Debian DLA-604-1 : ruby-actionpack-3.2 security update as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Debian Local Security Checks plugin family.
On the right side table select Debian DLA-604-1 : ruby-actionpack-3.2 security update plugin ID 93132.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl debian_DLA-604.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DLA-604.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - debian_DLA-604.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state debian_DLA-604.nasl -t <IP/HOST>

Go back to menu.
