Oracle Java SE 1.7.0_311 / 1.8.0_301 / 1.11.0_12 / 1.16.0_2 Multiple Vulnerabilities (Unix July 2021 CPU)

high Nessus Plugin ID 152021

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 7 Update 301, 8 Update 291, 11 Update 11, or 16 Update 1. It is, therefore, affected by multiple vulnerabilities as referenced in the July 2021 CPU advisory:

- Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Networking). Supported versions that are affected are Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle GraalVM Enterprise Edition: 20.3.2 and 21.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Oracle GraalVM Enterprise Edition accessible data. 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). (CVE-2021-2341)

- Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Library). Supported versions that are affected are Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle GraalVM Enterprise Edition: 20.3.2 and 21.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition. 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, Oracle GraalVM Enterprise Edition accessible data. 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). (CVE-2021-2369)

- Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Java SE: 8u291, 11.0.11, 16.0.1; Oracle GraalVM Enterprise Edition: 20.3.2 and 21.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Java SE, Oracle GraalVM Enterprise Edition. 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). (CVE-2021-2388)

- Vulnerability in the Java SE product of Oracle Java SE (component: JNDI). The supported version that is affected is Java SE: 7u301. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE. 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 can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. (CVE-2021-2432)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the July 2021 Oracle Critical Patch Update advisory.
