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

HTTPServerILServlet.java in JMS over HTTP Invocation Layer of the JbossMQ implementation, which is enabled by default in Red Hat Jboss Application Server <= Jboss 4.X does not restrict the classes for which it performs deserialization, which allows remote attackers to execute arbitrary code via crafted serialized data.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Jboss_enterprise_application_platform Redhat * 4.0 (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.
