CWEhttps://cwe.mitre.org/data/definitions/502.html

Apache Camel Netty enables Java deserialization by default. Apache Camel 2.22.x, 2.23.x, 2.24.x, 2.25.0, 3.0.0 up to 3.1.0 are affected. 2.x users should upgrade to 2.25.1, 3.x users should upgrade to 3.2.0.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Camel Apache 2.22.0 (including) 2.25.0 (including)
Camel Apache 3.0.0 (including) 3.1.0 (including)
Red Hat Fuse 7.8.0 RedHat camel-netty *

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.
