This module exploits an improper input validation issue in Atlassian Confluence, allowing arbitrary HTTP parameters to be translated into getter/setter sequences via the XWorks2 middleware and in turn allows for Java objects to be modified at run time. The exploit will create a new administrator user and upload a malicious plugins to get arbitrary code execution. All versions of Confluence between 8.0.0 through to 8.3.2, 8.4.0 through to 8.4.2, and 8.5.0 through to 8.5.1 are affected.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/multi/http/atlassian_confluence_rce_cve_2023_22515
msf exploit(atlassian_confluence_rce_cve_2023_22515) > show targets
...targets...
msf exploit(atlassian_confluence_rce_cve_2023_22515) > set TARGET < target-id >
msf exploit(atlassian_confluence_rce_cve_2023_22515) > show options
...show and set options...
msf exploit(atlassian_confluence_rce_cve_2023_22515) > exploit
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
