A deserialization of untrusted data in Fortinet FortiNAC below 7.2.1, below 9.4.3, below 9.2.8 and all earlier versions of 8.x allows attacker to execute unauthorized code or commands via specifically crafted request on inter-server communication port. Note FortiNAC versions 8.x will not be fixed.

Weakness

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

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.
