Published Jul 15, 2020
·
Updated

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle Java Runtime Environment. Interaction with the JavaFX library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the rendering of HTML in JavaFX. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.

Other sources

Vulnerability in the Java SE product of Oracle Java SE (component: JavaFX). The supported version that is affected is Java SE: 8u251. 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 and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. 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 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).
