IBM InfoSphere Information Server 11.7 is affected by a remote code execution vulnerability due to insecure deserialization in an RMI service. IBM X-Force ID: 255285.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Infosphere_information_server Ibm 11.7 (including) 11.7 (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.
