Vulnerability Information

Synopsis

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

Description

The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext. (CVE-2013-2566)

Impact

Remote attackers may be able to conduct plaintext-recovery attacks using statistical analysis of ciphertext.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K14638.

How to Run

Here is how to run the F5 Networks BIG-IP : TLS/SSL RC4 vulnerability (K14638) 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 : TLS/SSL RC4 vulnerability (K14638) plugin ID 78155.
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_SOL14638.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a f5_bigip_SOL14638.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_SOL14638.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_SOL14638.nasl -t <IP/HOST>

Go back to menu.
