CVE-2019-2821: Vulnerability in the Java SE component of Oracle Java SE (subcomponent: JSSE).

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: JSSE). Supported versions that are affected are Java SE: 11.0.3 and 12.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS 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 access to critical data or complete access to all 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 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N).

Security readout for executives and security teams

CVE-2019-2821 is a Java SE JSSE vulnerability affecting Java SE 11.0.3 and 12.0.1. The cited description says an unauthenticated network attacker could expose critical data through TLS, but exploitation is difficult and requires user interaction. The risk is mainly client-side Java that runs untrusted sandboxed code, not typical servers running only administrator-installed code. Most exposure is likely on endpoints or managed client environments running affected Java SE versions and untrusted sandboxed Java content. Server exposure appears lower when Java loads only trusted administrator-installed code, according to the source note. Handle as a moderate confidentiality risk. Patch affected Java runtimes through normal vulnerability management, with faster attention for client environments that still run untrusted Java content or depend on the Java sandbox. Mitigation focus: Apply the relevant Oracle, Ubuntu, or openSUSE Java security updates.; Prioritize systems running Java SE 11.0.3 or 12.0.1.; Reduce or remove untrusted Java Web Start or applet execution where possible..
