IBM WebSphere Application Server 8.5 and 9.0 could allow a remote attacker to execute arbitrary code on the system with a specially-crafted sequence of serialized objects from untrusted sources. IBM X-Force ID: 160445.
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 | 8.5.0.0 (including) | 8.5.5.15 (including) |
| Websphere_application_server | Ibm | 9.0.0.0 (including) | 9.0.0.11 (including) |
| Websphere_application_server | Ibm | 7.0.0.0 (including) | 7.0.0.0 (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.
