Title
Mescius ActiveReports.NET TypeResolutionService Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
Mescius ActiveReports.NET TypeResolutionService Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Mescius ActiveReports.NET. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the TypeResolutionService class. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25397.
Severity ?
9.8 (Critical)
