The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 7 Update 321, 8 Update 311, 11 Update 13, or 17 Update 1. It is, therefore, affected by multiple vulnerabilities as referenced in the October 2021 CPU advisory:
Vulnerability in the Java SE product of Oracle Java SE (component: JavaFX (libxml)). The supported version that is affected is Java SE: 8u301. 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 ability to cause a hang or frequently repeatable crash (complete DOS) of Java SE as well as unauthorized update, insert or delete access to some of Java SE accessible data and unauthorized read access to a subset of Java SE 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-2021-3517)
Vulnerability in the Java SE product of Oracle Java SE (component: Deployment). The supported version that is affected is Java SE: 8u301. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover 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 does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). (CVE-2021-35560)
Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. Easily exploitable vulnerability allows low privileged attacker with network access via Kerberos to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Oracle GraalVM Enterprise Edition, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java SE, Oracle GraalVM Enterprise Edition accessible data. (CVE-2021-35567)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
