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

An issue was discovered in SmartBear ReadyAPI SoapUI Pro 3.2.5. Due to unsafe use of an Java RMI based protocol in an unsafe configuration, an attacker can inject malicious serialized objects into the communication, resulting in remote code execution in the context of a client-side Network Licensing Protocol component.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Readyapi Smartbear 3.2.5 (including) 3.2.5 (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.
