Description
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.

Can you explain this vulnerability to me?

This vulnerability is a critical remote code execution flaw in the Mescius ActiveReports.NET software, specifically in the TypeResolutionService class. It occurs because the software does not properly validate user-supplied data, leading to deserialization of untrusted data. This allows a remote attacker to execute arbitrary code within the context of the current process. Exploitation requires interaction with the ActiveReports.NET library, but the exact attack methods may vary depending on how the software is implemented. [1]


How can this vulnerability impact me? :

Exploiting this vulnerability can allow remote attackers to execute arbitrary code on affected systems without needing any privileges or user interaction. This can compromise the confidentiality, integrity, and availability of the system, potentially leading to full system compromise or disruption of services. [1]
