CVE-2019-2989: Oracle Corporation Java vulnerability

CVE-2019-2989: 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. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded 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 can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS v3.0 Base Score 6.8 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N).

Security readout for executives and security teams

CVE-2019-2989 is a Java SE networking flaw that can let an unauthenticated network attacker alter data accessible to the Java runtime. Oracle describes exploitation as difficult, but the impact is serious where Java runs untrusted code or exposed services feed data into affected networking APIs. Exposure is most likely in legacy Java client deployments using sandboxed Java Web Start or Java applets, Java services consuming remote data through networking APIs, and products bundling affected Java runtimes. Downstream OpenJDK packages from Linux vendors may also be relevant. Treat this as a targeted remediation item, not an emergency based on current evidence. Prioritize systems running affected Java with untrusted code paths, internet-facing services, or business-critical data integrity requirements. Standard Java patch programs should cover most exposure. Mitigation focus: Apply Oracle October 2019 CPU or applicable vendor Java/OpenJDK security updates.; Replace affected Java SE and Java SE Embedded versions identified in the bundle.; Disable or restrict untrusted Java Web Start and applet execution where still present..
