Description

F5 BIG-IP Exploit Using CVE-2022-1388 and CVE-2022-41800

Readme

# Tippa My Tongue

Tippa My Tongue is an exploit that uses CVE-2022-1388 and CVE-2022-41800 to establish a `root` reverse shell on F5 BIG-IP products. Most CVE-2022-1388 exploits achieve code execution using `/mgmt/tm/util/bash`. However, this exploit uses `/mgmt/shared/iapp/rpm-spec-creator`, followed by `/mgmt/shared/iapp/build-package`. This approach was first suggested by [Ron Bowes](https://github.com/rbowes-r7) in this AttackerKB [analysis](https://attackerkb.com/topics/SN5WCzYO7W/cve-2022-1388/rapid7-analysis). Although, to my knowledge, no one ever published a CVE-2022-1388 exploit that did just that.
