IBM WebSphere Application Server Liberty OpenID Connect could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization. By sending a specially-crafted request to the RP service, an attacker could exploit this vulnerability to execute arbitrary code. IBM X-Force ID: 150999.

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 * 18.0.0.3 (excluding)

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.
