What is CVE-2020-15777?

An issue in the Maven Extension plugin for Gradle Enterprise allows for potentially malicious remote code execution due to inappropriate handling of serialized Java objects. The plugin utilizes a socket connection that is not restricted to a defined allow-list for deserialization, enabling attackers to exploit this weakness via a crafted deserialization gadget chain. Furthermore, the socket is not limited to localhost, which raises concerns about unauthorized access. The randomness of the socket's assigned port adds another layer of complexity, making it critical for users to secure their environments against potential attacks leveraging this vulnerability.
