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

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 could allow remote attackers to execute arbitrary Java code through the SOAP connector with a serialized object from untrusted sources. IBM X-Force ID: 143024.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Websphere_application_server Ibm 7.0.0.0 (including) 7.0.0.45 (including)
Websphere_application_server Ibm 8.0.0.0 (including) 8.0.0.15 (including)
Websphere_application_server Ibm 8.5.0.0 (including) 8.5.5.14 (including)
Websphere_application_server Ibm 9.0.0.0 (including) 9.0.0.9 (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.
