Vulnerabilities > CVE-2022-41479 - Authorization Bypass Through User-Controlled Key vulnerability in Devexpress Asp.Net web Forms Controls 19.2.3
Attack vector
NETWORK Attack complexity
LOW Privileges required
NONE Confidentiality impact
HIGH Integrity impact
NONE Availability impact
NONE Summary
The DevExpress Resource Handler (ASPxHttpHandlerModule) in DevExpress ASP.NET Web Forms Build v19.2.3 does not verify the referenced objects in the /DXR.axd?r= HTTP GET parameter. This leads to an Insecure Direct Object References (IDOR) vulnerability which allows attackers to access the application source code. NOTE: the vendor disputes this because the retrieved source code is only the DevExpress client-side application code that is, of course, intentionally readable by web browsers (a site's custom code and data is never accessible via an IDOR approach).
