CVSS: 4.3EPSS: 0%CPEs: 4EXPL: 0CVE-2023-39418 – Postgresql: merge fails to enforce update or select row security policies
https://notcve.org/view.php?id=CVE-2023-39418
A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows. Se encontró una vulnerabilidad en PostgreSQL con el uso del comando MERGE, que no puede probar nuevas filas con las políticas de seguridad de filas definidas para ACTUALIZAR y SELECCIONAR. Si las políticas ACTUALIZAR y SELECCIONAR prohíben algunas filas que las políticas INSERTAR no prohíben, un usuario podría almacenar dichas filas. • https://access.redhat.com/errata/RHSA-2023:7785 https://access.redhat.com/errata/RHSA-2023:7883 https://access.redhat.com/errata/RHSA-2023:7884 https://access.redhat.com/errata/RHSA-2023:7885 https://access.redhat.com/security/cve/CVE-2023-39418 https://bugzilla.redhat.com/show_bug.cgi?id=2228112 https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=cb2ae5741f2458a474ed3c31458d242e678ff229 https://security.netapp.com/advisory/ntap-20230915-0002 https://www.debian.org/security •

https://notcve.org/view.php?id=CVE-2023-39417
IN THE EXTENSION SCRIPT, a SQL Injection vulnerability was found in PostgreSQL if it uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct (dollar quoting, '', or ""). If an administrator has installed files of a vulnerable, trusted, non-bundled extension, an attacker with database-level CREATE privilege can execute arbitrary code as the bootstrap superuser. EN EL SCRIPT DE EXTENSIÓN, se encontró una vulnerabilidad de inyección SQL en PostgreSQL si usa @extowner@, @extschema@ o @extschema:...@ dentro de una construcción de cotización (cotización en dólares, '' o ""). Si un administrador ha instalado archivos de una extensión vulnerable, de confianza y no empaquetada, un atacante con privilegios CREATE de nivel de base de datos puede ejecutar código arbitrario como superusuario de arranque. • https://access.redhat.com/errata/RHSA-2023:7545 https://access.redhat.com/errata/RHSA-2023:7579 https://access.redhat.com/errata/RHSA-2023:7580 https://access.redhat.com/errata/RHSA-2023:7581 https://access.redhat.com/errata/RHSA-2023:7616 https://access.redhat.com/errata/RHSA-2023:7656 https://access.redhat.com/errata/RHSA-2023:7666 https://access.redhat.com/errata/RHSA-2023:7667 https://access.redhat.com/errata/RHSA-2023:7694 https://access.redhat.com/errata/RHSA • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •

CVSS: 5.4EPSS: 0%CPEs: 9EXPL: 0CVE-2023-2455 – postgresql: row security policies disregard user ID changes after inlining.
https://notcve.org/view.php?id=CVE-2023-2455
Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. A flaw was found in PostgreSQL, which could permit incorrect policies being applied in certain cases where role-specific policies are used and a given query is planned under one role and executed under other roles. • https://access.redhat.com/security/cve/CVE-2023-2455 https://security.netapp.com/advisory/ntap-20230706-0006 https://www.postgresql.org/support/security/CVE-2023-2455 https://bugzilla.redhat.com/show_bug.cgi?id=2207569 • CWE-20: Improper Input Validation •
