CVE-2019-2945: Oracle Corporation Java vulnerability

CVE-2019-2945: Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking).

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking). 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 ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. 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 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L).

Security readout for executives and security teams

CVE-2019-2945 is a low-severity Oracle Java networking issue that can let an unauthenticated network attacker cause a limited denial of service. The main concern is older Java client deployments that run untrusted sandboxed Java Web Start applications or Java SE 8 applets. The source explicitly says typical trusted-code server deployments are not affected. Exposure is most likely in legacy desktop or embedded Java environments that still permit untrusted sandboxed Java code from the internet. Server-side Java applications that load only administrator-installed trusted code are described as outside scope. Treat this as a hygiene and legacy-client remediation item, not an emergency. Business urgency rises if the organization still uses Java applets, Web Start, or embedded Java that loads untrusted code. Patch during normal vulnerability cycles unless those conditions exist broadly. Mitigation focus: Inventory Java SE and Java SE Embedded versions against the affected releases.; Apply relevant Oracle or OpenJDK vendor security updates for affected Java deployments.; Reduce or disable use of untrusted Java Web Start applications and applets..
