Description
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 27; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

AI Analysis

Impact

The vulnerability resides in the Java Secure Socket Extension (JSSE) component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. An unauthenticated attacker who can reach the affected system over TLS can interfere with data integrity that the product can access. Successful exploitation allows unauthorized updates, insertions, or deletions of data, as indicated by the CVSS vector showing a low integrity impact. The weaknesses are reflected by CWE‑200 (Information Exposure) and CWE‑295 (Improper Handling of TLS or SSL).

Affected Systems

Affected are Oracle Java SE versions 8u503, 8u503‑perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, and 27; Oracle GraalVM for JDK versions 17.0.20.1 and 21.0.12.1; and Oracle GraalVM Enterprise Edition 21.3.19.1.1.

Risk and Exploitability

The CVSS base score of 3.7 indicates a low severity risk with only integrity impairment. The EPSS score of less than 1% denotes a very low probability of exploitation, and the vulnerability is not listed in the CISA KEV catalog, meaning no confirmed widespread exploitation has been reported. Attackers need only network access over TLS and no authentication to target vulnerable instances, but crafting an exploit is difficult. Until a patch is applied, the risk remains modest, but organizations should monitor for anomalous data changes and promptly apply Oracle security updates.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the Oracle security patch or upgrade to a non‑vulnerable version for Java SE, GraalVM for JDK, and GraalVM Enterprise Edition.
  • Restrict inbound TLS connections to trusted hosts or networks if the application does not require open access.
  • Enable auditing or logging of data modification operations in applications that rely on the vulnerable Java components to detect unauthorized changes.
