CoreResponseStateManager in Apache MyFaces Trinidad 1.0.0 through 1.0.13, 1.2.x before 1.2.15, 2.0.x before 2.0.2, and 2.1.x before 2.1.2 might allow attackers to conduct deserialization attacks via a crafted serialized view state string.

Weakness

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

Affected Software

NameVendorStart VersionEnd Version
Myfaces_trinidadApache1.0.0 (including)1.0.13 (excluding)
Myfaces_trinidadApache1.2.0 (including)1.2.15 (excluding)
Myfaces_trinidadApache2.0.0 (including)2.0.2 (excluding)
Myfaces_trinidadApache2.1.0 (including)2.1.2 (excluding)

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.
