F5-BIGIP-Decoder

Detecting and decoding BIG IP cookies in bash

Bash script to print out private IPs, ports and other stuff from F5's BIG IP Loadbalancers -- from not encrypted cookies which is still the default. It detects all cookies, also the AES encrypted ones.

Usage

f5_bigip_decoder.sh <URL> or f5_bigip_decoder.sh <cookie value> or f5_bigip_decoder.sh <cookie name=cookie value>

Example

f5_bigip_decoder.sh TEST gives you an idea by running it against a predefined header

Caveats

I didn't spend much time to make the code beautiful.
