PostgreSQL Improper Neutralization of Special Elements used in an OS Command (OS Command Injection) Vulnerability - CVE-2019-9193

DISPUTED In PostgreSQL 9.3 through 11.2 the quotCOPY TO/FROM PROGRAMquot function allows superusers and users in the 39pg_execute_server_program39 group to execute arbitrary code in the context of the database39s operating system user. This functionality is enabled by default and can be abused to run arbitrary operating system commands on Windows Linux and macOS. NOTE: Third parties claim/state this is not an issue because PostgreSQL functionality for COPY TO/FROM PROGRAM is acting as intended. References state that in PostgreSQL a superuser can execute commands as the server user without using the COPY FROM PROGRAM.
