Telerik Report Server Auth Bypass



This module exploits an authentication bypass vulnerability in Telerik Report Server versions and prior which allows an unauthenticated attacker to create a new account with administrative privileges. The vulnerability leverages the initial setup page which is still accessible once the setup process has completed. If either USERNAME or PASSWORD are not specified, then a random value will be selected. The module will fail if the specified USERNAME already exists.

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