console, perform a telnet handshake, and send fork commands to download and execute malicious Java code, establishing a reverse shell connection.
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the RCE vulnerability in Eclipse Equinox OSGi versions 3.8 through 3.18 by applying vendor patches or upgrading to unaffected versions.
Prevents remote attackers from reaching the vulnerable OSGi telnet console by monitoring and controlling communications at system boundaries, such as blocking telnet traffic.
Eliminates the unauthenticated fork command attack surface by disabling the non-essential OSGi console interface.
Security SummaryAI
CVE-2023-54342 is a remote code execution vulnerability in the console interface of Eclipse Equinox OSGi versions 3.8 through 3.18. The flaw stems from the fork command functionality, which allows unauthenticated attackers to execute arbitrary code. It has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-306 (Missing Authentication for Critical Function).
Unauthenticated remote attackers can exploit this vulnerability by establishing a telnet connection to the exposed OSGi console, completing the telnet handshake, and issuing fork commands. This enables them to download and execute malicious Java code, such as establishing a reverse shell, with low attack complexity and no privileges or user interaction required.
