In Progress® Telerik® Report Server, versions prior to 2025 Q1 (11.0.25.211) when using the older .NET Framework implementation, communication of non-sensitive information between the service agent process and app host process occurs over an unencrypted tunnel, which can be subjected to local network traffic sniffing.
In Progress® Telerik® Report Server versions prior to 2024 Q4 (10.3.24.1112), the encryption of local asset data used an older algorithm which may allow a sophisticated actor to decrypt this information.
In Progress Telerik Report Server versions prior to 2024 Q3 (10.2.24.924), a remote code execution attack is possible through object injection via an insecure type resolution vulnerability.
