CVSS: 7.2EPSS: 0%CPEs: 76EXPL: 0CVE-2017-12172 – postgresql: Start scripts permit database administrator to modify root-owned files
https://notcve.org/view.php?id=CVE-2017-12172
PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. • http://www.securityfocus.com/bid/101949 http://www.securitytracker.com/id/1039752 https://access.redhat.com/errata/RHSA-2017:3402 https://access.redhat.com/errata/RHSA-2017:3403 https://access.redhat.com/errata/RHSA-2017:3404 https://access.redhat.com/errata/RHSA-2017:3405 https://www.postgresql.org/about/news/1801 https://www.postgresql.org/support/security https://access.redhat.com/security/cve/CVE-2017-12172 https://bugzilla.redhat.com/show_bug.cgi?id=1498394 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. PostgreSQL en sus versiones anteriores a 9.2.22, 9.3.18, 9.4.13, 9.5.8 y 9.6.4 es vulnerable a un fallo de autorización que permite que los atacantes remotos autenticados recuperen contraseñas de los mapeos de usuarios definidos por los propietarios del servidor extranjero sin tener privilegios para ello. An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. • http://www.debian.org/security/2017/dsa-3935 http://www.debian.org/security/2017/dsa-3936 http://www.securityfocus.com/bid/100275 http://www.securitytracker.com/id/1039142 https://access.redhat.com/errata/RHSA-2017:2677 https://access.redhat.com/errata/RHSA-2017:2678 https://access.redhat.com/errata/RHSA-2017:2728 https://security.gentoo.org/glsa/201710-06 https://www.postgresql.org/about/news/1772 https://access.redhat.com/security/cve/CVE-2017-7547 https:// • CWE-522: Insufficiently Protected Credentials •
