Telerik Report Server Auth Bypass and Deserialization RCE



This module chains an authentication bypass vulnerability (CVE-2024-4358) with a deserialization vulnerability (CVE-2024-1800) to obtain remote code execution against Telerik Report Server version and prior. The authentication bypass flaw allows an unauthenticated user to create a new user with administrative privileges. The USERNAME datastore option can be used to authenticate with an existing account to prevent the creation of a new one. The deserialization flaw works by uploading a specially crafted report that when loaded will execute an OS command as NT AUTHORITY\SYSTEM. The module will automatically delete the created report but not the account because users are unable to delete themselves.

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 exploit/windows/http/telerik_report_server_deserialization
msf exploit(telerik_report_server_deserialization) > show targets
msf exploit(telerik_report_server_deserialization) > set TARGET < target-id >
msf exploit(telerik_report_server_deserialization) > show options
    ...show and set options...
msf exploit(telerik_report_server_deserialization) > 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.
