SAP Business Objects Business Intelligence Platform (CrystalReports WebForm Viewer), versions 4.1, 4.2, and Crystal Reports for VS version 2010, allows an attacker with basic authorization to perform deserialization attack in the application, leading to service interruptions and denial of service and unauthorized execution of arbitrary commands, leading to Deserialization of Untrusted Data.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Businessobjects_business_intelligence_platform | Sap | 4.1 (including) | 4.1 (including) |
| Businessobjects_business_intelligence_platform | Sap | 4.2 (including) | 4.2 (including) |
| Crystal_reports_for_visual_studio | Sap | 2010 (including) | 2010 (including) |
Potential Mitigations
- Make fields transient to protect them from deserialization.
- An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
