Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated mongodb and pymongo packages that fix two security issues and add one enhancement are now available for Red Hat Enterprise MRG 2.3 for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

MongoDB is a NoSQL database. PyMongo provides tools for working with MongoDB.

A flaw was found in the run() function implementation in MongoDB. A database user permitted to send database queries to a MongoDB server could use this flaw to crash the server or, possibly, execute arbitrary code with the privileges of the mongodb user. (CVE-2013-1892)

A NULL pointer dereference flaw was found in PyMongo. An invalid DBRef record received from a MongoDB server could cause an application using PyMongo to crash. (CVE-2013-2132)

Note: In Red Hat Enterprise MRG Grid, MongoDB is not accessed by users directly and is only accessed by other Grid services, such as Condor and Cumin.

This update also adds the following enhancement :

* Previously, MongoDB was configured to listen for connections on all network interfaces. This could allow remote users to access the database if the firewall was configured to allow access to the MongoDB port (access is blocked by the default firewall configuration in Red Hat Enterprise Linux). This update changes the configuration to only listen on the loopback interface by default. (BZ#892767)

Users of Red Hat Enterprise MRG 2.3 for Red Hat Enterprise Linux 6 are advised to upgrade to these updated packages, which contain backported patches to resolve these issues and add this enhancement. After installing this update, MongoDB will be restarted automatically.

Solution

Update the affected packages.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB, Core Impact)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the RHEL 6 : mongodb and pymongo (RHSA-2013:1170) vulnerability:

Metasploit: exploit/linux/misc/mongod_native_helper
[MongoDB nativeHelper.apply Remote Code Execution]
Exploit-DB: exploits/linux/remote/24935.rb

How to Run

Here is how to run the RHEL 6 : mongodb and pymongo (RHSA-2013:1170) 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 Red Hat Local Security Checks plugin family.
On the right side table select RHEL 6 : mongodb and pymongo (RHSA-2013:1170) plugin ID 76662.
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 redhat-RHSA-2013-1170.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2013-1170.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - redhat-RHSA-2013-1170.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 redhat-RHSA-2013-1170.nasl -t <IP/HOST>

Go back to menu.
