CVE-2022-36119

An issue was discovered in Blue Prism Enterprise 6.0 through 7.01. In a misconfigured environment that exposes the Blue Prism Application server, it is possible for a domain authenticated user to send a crafted message to the Blue Prism Server and accomplish a remote code execution attack that is possible because of insecure deserialization. Exploitation of this vulnerability allows for code to be executed in the context of the Blue Prism Server service.

Weakness

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

Affected Software

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.
