CVSS: 7.0EPSS: 0%CPEs: 11EXPL: 0CVE-2018-1053 – postgresql: pg_upgrade creates file of sensitive metadata under prevailing umask
https://notcve.org/view.php?id=CVE-2018-1053
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file. En postgresql, en versiones 9.3.x anteriores a la 9.3.21, versiones 9.4.x anteriores a la 9.4.16, versiones 9.5.x anteriores a la 9.5.11, versiones 9.6.x anteriores a la 9.6.7 y en versiones 10.x anteriores a la 10.2, pg_upgrade crea archivos en el directorio de trabajo actual que contienen la salida de "pg_dumpall -g" bajo umask, que estaba en funcionamiento cuando el usuario invocó a pg_upgrade y no bajo 0077, que es el directorio que se suele emplear para otros archivos temporales. Esto puede permitir que un atacante autenticado lea o modifique un archivo que puede contener contraseñas cifradas o sin cifrar de la base de datos. • http://www.securityfocus.com/bid/102986 https://access.redhat.com/errata/RHSA-2018:2511 https://access.redhat.com/errata/RHSA-2018:2566 https://access.redhat.com/errata/RHSA-2018:3816 https://lists.debian.org/debian-lts-announce/2018/02/msg00006.html https://usn.ubuntu.com/3564-1 https://www.postgresql.org/about/news/1829 https://access.redhat.com/security/cve/CVE-2018-1053 https://bugzilla.redhat.com/show_bug.cgi?id=1539619 • CWE-377: Insecure Temporary File CWE-732: Incorrect Permission Assignment for Critical Resource •

https://notcve.org/view.php?id=CVE-2017-15099
INSERT ... ON CONFLICT DO UPDATE commands in PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, and 9.5.x before 9.5.10 disclose table contents that the invoker lacks privilege to read. These exploits affect only tables where the attacker lacks full read access but has both INSERT and UPDATE privileges. Exploits bypass row level security policies and lack of SELECT privilege.
