Joomla API Improper Access Checks



Joomla versions between 4.0.0 and 4.2.7, inclusive, contain an improper API access vulnerability. This vulnerability allows unauthenticated users access to webservice endpoints which contain sensitive information. Specifically for this module we exploit the users and config/application endpoints. This module was tested against Joomla 4.2.7 running on Docker.

Module Options

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/joomla_api_improper_access_checks
msf auxiliary(joomla_api_improper_access_checks) > show actions
msf auxiliary(joomla_api_improper_access_checks) > set ACTION < action-name >
msf auxiliary(joomla_api_improper_access_checks) > show options
    ...show and set options...
msf auxiliary(joomla_api_improper_access_checks) > 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.
