Descriptions

In PostgreSQL 9.3 through 11.2, the "COPY TO/FROM PROGRAM" function allows superusers and users in the 'pg_execute_server_program' group to execute arbitrary code in the context of the database's 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’.

** EN DISPUTA ** En PostgreSQL 9.3 a 11.2, la función "COPIAR HACIA / DESDE EL PROGRAMA" permite a los superusuarios y usuarios en el grupo 'pg_execute_server_program' ejecutar código arbitrario en el contexto del usuario del sistema operativo de la base de datos. Esta funcionalidad está habilitada de manera predeterminada y se puede abusar para ejecutar comandos arbitrarios del sistema operativo en Windows, Linux y macOS. NOTA: Los terceros reclaman / afirman que esto no es un problema porque la funcionalidad de PostgreSQL para "COPIAR HACIA / DESDE EL PROGRAMA" está actuando según lo previsto. Las referencias indican que en PostgreSQL, un superusuario puede ejecutar comandos como usuario del servidor sin usar la "COPIA DEL PROGRAMA".

PostgreSQL version 9.6.1 suffers from an authenticated remote code execution vulnerability.
