In some workflow of SAP BusinessObjects BI Platform (Central Management Console and BI LaunchPad), an authenticated attacker with low privileges can intercept a serialized object in the parameters and substitute with another malicious serialized object, which leads to deserialization of untrusted data vulnerability. This could highly compromise the Confidentiality, Integrity, and Availability of the system.

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 Sap 4.2 (including) 4.2 (including)
Businessobjects_business_intelligence Sap 4.3 (including) 4.3 (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.
