Atlassian Confluence Administrator Code Macro Remote Code Execution

This module exploits an authenticated administrator-level vulnerability in Atlassian Confluence,
tracked as CVE-2024-21683. The vulnerability exists due to the Rhino script engine parser evaluating
tainted data from uploaded text files. This facilitates arbitrary code execution. This exploit will
authenticate, validate user privileges, extract the underlying host OS information, then trigger
remote code execution. All versions of Confluence prior to 7.17 are affected, as are many versions
up to 8.9.0.
