CVE-2023-54342 -- CVSS 9.8 Vulnerability Briefing

CVE-2023-54342 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2023-54342 is a remote code execution vulnerability in the console interface of Eclipse Equinox OSGi, affecting versions 3.8 through 3.18 of the open-source OSGi framework runtime widely used in Java-based enterprise and embedded applications.

Technical Detail

The flaw resides in the Equinox OSGi console interface, which fails to enforce authentication before processing incoming connections, allowing an unauthenticated remote attacker to interact directly with the console. By sending crafted input to this interface, an attacker can execute arbitrary code in the context of the process running the OSGi framework. Successful exploitation results in full RCE with the privileges of the hosting application or service, potentially enabling complete system compromise depending on deployment context.

Exploitation Status

No known exploit code has been publicly observed or confirmed as of May 12, 2026. This vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, and there is no evidence of active exploitation in the wild at this time. The CVSS score of 9.8 reflects the severity of the attack vector and impact, not confirmed exploitation activity.

Who Is Targeting This

No specific threat actor attribution at this time. No campaigns, targeted sectors, or adversary groups have been linked to exploitation of this vulnerability in available intelligence reporting.

What To Do

Organizations running Eclipse Equinox OSGi versions 3.8 through 3.18 should prioritize upgrading to a patched release as soon as one is confirmed available from the Eclipse Foundation. As an immediate workaround, administrators should disable or restrict network access to the Equinox OSGi console interface, particularly ensuring it is not exposed on untrusted or public-facing network segments. Firewall rules or host-based controls should be used to limit console access to authorized management hosts only. Given the unauthenticated attack surface and critical CVSS rating, this should be treated as a high-priority remediation item even in the absence of confirmed active exploitation.
