Technical Analysis
So far, 2024 has seen a few notable vulnerabilities, such as CVE-2024-1709, that attack setup wizard flows for authentication bypass. This vulnerability, discovered by researcher Sina Kheirkhah, falls into the same group. By exploiting an access control vulnerability in the administrator setup wizard, unauthenticated attackers gain high-privileged access to Telerik Report Server. With the newly-acquired administrator account, another new Report Server vulnerability, tracked as CVE-2024-1800, can be leveraged for remote code execution on the host system.
Exploitation
The initial administrator setup code in Telerik.ReportServer.Web.dll!Telerik.ReportServer.Web.Controllers.StartupController.Register
does not check if setup has already been completed. As a result, the attacker can manually perform the web request to create a new administrator account. Per Sina’s public proof of concept, the authentication bypass vulnerability can be exploited with a single request:
curl 'http://TARGET_HERE/Startup/Register' -d 'Username=USERNAME_HERE&Password=PASSWORD_HERE&ConfirmPassword=PASSWORD_HERE&Email=backdoor%40admin.com&FirstName=backdoor&LastName=user'
Public Exposure
It’s worth mentioning that Shodan only appears to return a few hundred public-facing Telerik Report Server instances. However, due to the unauthenticated RCE impact, organizations running the Report Server would be wise to patch with urgency. The Progress Knowledge Base contains guidance on how to remediate this vulnerability.
