Supported versions that are affected are Java SE: 6u141, 7u131 and 8u121; Java SE Embedded: 8u121; JRockit: R28.3.13. Difficult to exploit vulnerability allows unauthenticated attacker with network access via FTP to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded, JRockit accessible data. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N). ### From the Ubuntu Security Team It was discovered that the FTP client implementation in OpenJDK did not properly sanitize user inputs.
