CVE-2018-2581 Explained : Impact and Mitigation

A vulnerability has been discovered in the Java SE component of Oracle Java SE, specifically in the JavaFX subcomponent. The affected versions are Java SE 7u161, 8u152, and 9.0.1. This vulnerability can be easily exploited by an unauthenticated attacker who has network access through multiple protocols. It allows them to compromise Java SE. However, successful attacks require interaction from a person other than the attacker. Although the vulnerability is in Java SE, it can have significant impacts on other products. Exploiting this vulnerability can lead to unauthorized read access to a portion of Java SE data. It's important to note that this vulnerability is applicable to Java deployments in clients, such as sandboxed Java Web Start applications or sandboxed Java applets, which run untrusted code from the internet and rely on the Java sandbox for security. The CVSS 3.0 Base Score for this vulnerability is 4.7, with a confidentiality impact.
