CVE-2024-28777

IBM Cognos Controller 11.0.0 through 11.0.1 FP3 and IBM Controller 11.1.0

is vulnerable to unrestricted deserialization. This vulnerability allows users to execute arbitrary code, escalate privileges, or cause denial of service attacks by exploiting the unrestricted deserialization of types in the application.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

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.
