CVE-2023-54342
Eclipse Equinox OSGi versions 3.8 through 3.18 contain a remote code execution vulnerability in the console interface that allows unauthenticated attackers to execute arbitrary code by exploiting the fork command functionality. Attackers can establish a telnet connection to the OSGi console, perform a telnet handshake, and send fork commands to download and execute malicious Java code, establishing a reverse shell connection.

Eclipse Equinox is the core OSGi runtime used in many Java enterprise applications and the Eclipse IDE itself. A CVSS 9.8 unauthenticated RCE via a common protocol like telnet in a foundational library justifies high visibility.
