Existe una vulnerabilidad de divulgación de información en Progress Telerik Report Server, versión 2024 Q1 (10.0.24.305) o anterior, que permite a un atacante con pocos privilegios leer archivos del sistema a través del procesamiento de entidades externas XML.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Progress Software Telerik Reporting. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the implementation of ValidateMetadaUri method. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of SYSTEM.
