CVE-2023-5763Network attack vector

Remote code execution via insecure ORB listeners

Published Nov 3, 2023 · Updated Sep 5, 2024

Remote code execution in Eclipse GlassFish 5.0 through 5.1 and 6.0.0 through 6.2.5 allows remote attackers to load malicious code. Eclipse identifies insecure ORB listeners as the entry point but does not disclose the input path or code-loading operation. Reachability requires an enabled insecure ORB listener, a JDK below the stated update thresholds, and unspecified user interaction; execution affects the server process.
