Exploited by Malware: True

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The byte-range filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial-of-service (memory and CPU consumption) using a Range header that expresses multiple overlapping ranges.

When this vulnerability is exploited, the httpd process consumes all available CPU cycles. As a result of CPU starvation, the Configuration utility, SSH sessions, and other userland processes may appear extremely slow or completely unresponsive. On BIG-IP systems, if the system hardware watchdog timer is not updated for more than 10 seconds, the hardware watchdog restarts the system. (CVE-2011-3192)

Impact

The performance of userland processes may be severely impaired, and the system may eventually reboot.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K13114.

How to Run

Here is how to run the F5 Networks BIG-IP : Apache Range header vulnerability (K13114) 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 F5 Networks Local Security Checks plugin family.
On the right side table select F5 Networks BIG-IP : Apache Range header vulnerability (K13114) plugin ID 78131.
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 f5_bigip_SOL13114.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a f5_bigip_SOL13114.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - f5_bigip_SOL13114.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 f5_bigip_SOL13114.nasl -t <IP/HOST>

Go back to menu.
