Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. 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 read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), 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. CVSS 3.0 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).
This is a vulnerability exploitable with network access which means the vulnerable software is bound to
the network stack and the attacker does not require local network access or local access to exploit it.
Such a vulnerability is often termed “remotely exploitable”.
The access conditions are somewhat specialized; the following are examples:
The attacking party is limited to a group of systems or users at some level of authorization, possibly untrusted.
Some information must be gathered before a successful attack can be launched.
The affected configuration is non-default, and is not commonly configured (e.g., a vulnerability present when a
server performs user account authentication via a specific scheme, but not present for another authentication scheme).
The attack requires a small amount of social engineering that might occasionally fool cautious users (e.g.,
phishing attacks that modify a web browser’s status bar to show a false link, having to be on someone’s “buddy”
list before sending an IM exploit).
Authentication is not required to access and exploit the vulnerability.
There is considerable informational disclosure. Access to some system files is
possible, but the attacker does not have control over what is obtained, or the scope of
the loss is constrained. An example is a vulnerability that divulges only certain tables
in a database.
There is no impact to the integrity of the system.
There is no impact to the availability of the system.
