This module scans for an unauthenticated RCE vulnerability which exists in Apache version 2.4.49 (CVE-2021-41773). If files outside of the document root are not protected by ‘require all denied’ and CGI has been explicitly enabled, it can be used to execute arbitrary commands (Remote Command Execution). This vulnerability has been reintroduced in Apache 2.4.50 fix (CVE-2021-42013).
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/scanner/http/apache_normalize_path
msf auxiliary(apache_normalize_path) > show actions
...actions...
msf auxiliary(apache_normalize_path) > set ACTION < action-name >
msf auxiliary(apache_normalize_path) > show options
...show and set options...
msf auxiliary(apache_normalize_path) > run
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.
