CVE-2020-1964

It was noticed that Apache Heron 0.20.2-incubating, Release 0.20.1-incubating, and Release v-0.20.0-incubating does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerabilities (CWE-502: Deserialization of Untrusted Data).

Weakness

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

Affected Software

Name	Vendor	Start Version	End Version
Heron	Apache	0.20.0-incubating (including)	0.20.0-incubating (including)
Heron	Apache	0.20.1-incubating (including)	0.20.1-incubating (including)
Heron	Apache	0.20.2-incubating (including)	0.20.2-incubating (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.
