A series of deserialization vulnerabilities have been discovered in Codehaus 1.9.x implemented in EAP 7. This CVE fixes CVE-2017-17485, CVE-2017-7525, CVE-2017-15095, CVE-2018-5968, CVE-2018-7489, CVE-2018-1000873, CVE-2019-12086 reported for FasterXML jackson-databind by implementing a whitelist approach that will mitigate these vulnerabilities and future ones alike.

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.
