CyberRota Analysis
AI-GeneratedA vulnerability in RESTEasy's SourceProvider allows unauthenticated attackers to exploit an XML External Entity (XXE) flaw, enabling remote file reads by sending specially crafted XML requests. This could lead to the exposure of sensitive file contents in the HTTP response, posing a significant risk to data confidentiality. Organizations using RESTEasy should prioritize patching this vulnerability to mitigate potential data breaches.
Original NVD Description
A flaw was found in RESTEasy's SourceProvider. This vulnerability allows an unauthenticated attacker to perform an unauthenticated remote file read. By sending a specially crafted XML body with a DOCTYPE declaration referencing external entities to an endpoint that accepts application/xml and returns Source or StreamSource, the server can be tricked into resolving the entity and including sensitive file contents in the HTTP response. This is due to the SourceProvider.writeTo() method creating a SAXParser without disabling external entity resolution, leading to an XML External Entity (XXE) vulnerability.
