Synopsis

OpenJDK is affected by multiple vulnerabilities.

Description

The version of OpenJDK installed on the remote host is prior to 7 <= 7u271 / 8 <= 8u262 / 11.0.0 <= 11.0.8 / 13.0.0 <= 13.0.4 / 15.0.0 <= 15.0.0. It is, therefore, affected by multiple vulnerabilities as referenced in the 2020-10-20 advisory.

Please Note: Java CVEs do not always include OpenJDK versions, but are confirmed separately by Tenable using the patch versions from the referenced OpenJDK security advisory.

 - Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 11.0.8 and 15. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability 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. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
 (CVE-2020-14803)

 - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Java SE: 7u271, 8u261, 11.0.8 and 15; Java SE Embedded: 8u261. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data as well as unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.1 Base Score 4.2 (Confidentiality and Integrity impacts). CVSS Vector:
 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N). (CVE-2020-14792)

 - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization).
 Supported versions that are affected are Java SE: 7u271, 8u261, 11.0.8 and 15; Java SE Embedded: 8u261.
 Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.
 Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service.
