A vulnerability was found in Maven Extension Plugin up to 1.5 on Gradle. It has been declared as critical. This vulnerability affects an unknown functionality of the component Socket Handler. The manipulation as part of a Serialized Java Object leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:
An issue was discovered in the Maven Extension plugin before 1.6 for Gradle Enterprise. It is vulnerable to, in the worst case, Remote Code Execution, and in the general case, local privilege escalation. Internally, the plugin uses a socket connection to send serialized Java objects that are deserialized by a Java standard library ObjectInputStream. This ObjectInputStream was not restricted to a list of trusted classes, thus allowing an attacker to send a malicious deserialization gadget chain to achieve code execution. The socket was not bound exclusively to localhost. The port this socket is assigned to is randomly selected by the JVM and is not intentionally exposed to the public (either by design or documentation).
The weakness was disclosed 08/25/2020 (Website). The advisory is shared for download at docs.gradle.com. This vulnerability was named CVE-2020-15777 since 07/15/2020. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.
Upgrading to version 1.6 eliminates this vulnerability.
