CVE-2018-2826: Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries).

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Libraries). The supported version that is affected is Java SE: 10. 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 3.0 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).

Security readout for executives and security teams

CVE-2018-2826 is a high-severity Oracle Java SE 10 issue affecting clients that run untrusted sandboxed Java Web Start applications or Java applets. Exploitation is difficult and requires user interaction, but success can result in takeover of Java SE with high confidentiality, integrity, and availability impact. Highest concern is endpoints or products using Java SE 10 to load untrusted Java Web Start applications or applets from the internet. Server-side Java workloads running only trusted code are described as not affected by this condition. Treat as high priority for legacy Java client environments, especially internet-sourced Java content. It is lower urgency for confirmed server-only trusted-code deployments, but still requires inventory proof and vendor update tracking. Mitigation focus: Identify Java SE 10 installations and legacy Java Web Start or applet use.; Apply Oracle, operating system, or appliance vendor security guidance and updates.; Disable or remove untrusted Java client execution where business workflows allow..
