CVE-2019-2422: Oracle Corporation Java vulnerability

CVE-2019-2422: Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries).

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries). Supported versions that are affected are Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. 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 unauthorized read access to a subset of Java SE 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 does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 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).

Security readout for executives and security teams

CVE-2019-2422 is a low-severity Java client-side sandbox issue. An attacker would need to convince a user to run untrusted sandboxed Java code, such as an applet or Java Web Start application. A successful attack could read limited Java-accessible data, not change data or cause outage. Exposure is most likely on legacy endpoints or applications that still run sandboxed Java applets, Java Web Start, or Java SE Embedded versions listed as affected. Server-side JVMs that only load trusted administrator-installed code are not identified as affected by Oracle's note. Treat this as a hygiene item, not an emergency, unless the organization still depends on legacy Java client technologies. Prioritize patching or retirement on internet-facing user workflows and managed endpoints where users may launch untrusted Java content. Mitigation focus: Apply Oracle or operating-system Java security updates covering the January 2019 CPU.; Upgrade affected Java SE 7u201, 8u192, 11.0.1, and Java SE Embedded 8u191 deployments.; Reduce or remove use of untrusted Java applets and Java Web Start applications..
