Overview

CVE-2020-15777 is a high-severity vulnerability. It was published on August 25, 2020 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

An issue was discovered in the Maven Extension plugin before 1.6 for Gradle Enterprise. The extension uses a socket connection to send serialized Java objects. Deserialization is not restricted to an allow-list, thus allowing an attacker to achieve code execution via a malicious deserialization gadget chain. The socket is not bound exclusively to localhost. The port this socket is assigned to is randomly selected and is not intentionally exposed to the public (either by design or documentation). This could potentially be used to achieve remote code execution and local privilege escalation.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
