CVSS: 4.4EPSS: 0%CPEs: 42EXPL: 0CVE-2023-5870 – Postgresql: role pg_signal_backend can signal certain superuser processes.
https://notcve.org/view.php?id=CVE-2023-5870
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack. Se encontró una falla en PostgreSQL que involucra la función pg_cancel_backend que señala a los trabajadores en segundo plano, incluido el iniciador de replicación lógica, los trabajadores de autovacuum y el iniciador de autovacuum. La explotación exitosa requiere una extensión no central con un trabajador en segundo plano menos resistente y afectaría únicamente a ese trabajador en segundo plano específico. • 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-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-21469
An issue was discovered in PostgreSQL 12.2 allows attackers to cause a denial of service via repeatedly sending SIGHUP signals. NOTE: this is disputed by the vendor because untrusted users cannot send SIGHUP signals; they can only be sent by a PostgreSQL superuser, a user with pg_reload_conf access, or a user with sufficient privileges at the OS level (the postgres account or the root account). • https://www.postgresql.org/message-id/CAA8ZSMqAHDCgo07hqKoM5XJaoQy6Vv76O7966agez4ffyQktkA%40mail.gmail.com https://www.postgresql.org/message-id/flat/CAA8ZSMqAHDCgo07hqKoM5XJaoQy6Vv76O7966agez4ffyQktkA%40mail.gmail.com https://www.postgresql.org/support/security • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2023-32305 – aiven-extras PostgreSQL Privilege Escalation Through Overloaded Search Path
https://notcve.org/view.php?id=CVE-2023-32305
aiven-extras is a PostgreSQL extension. Versions prior to 1.1.9 contain a privilege escalation vulnerability, allowing elevation to superuser inside PostgreSQL databases that use the aiven-extras package. The vulnerability leverages missing schema qualifiers on privileged functions called by the aiven-extras extension. A low privileged user can create objects that collide with existing function names, which will then be executed instead. Exploiting this vulnerability could allow a low privileged user to acquire `superuser` privileges, which would allow full, unrestricted access to all data and database functions. • https://github.com/aiven/aiven-extras/commit/8682ae01bec0791708bf25791786d776e2fb0250 https://github.com/aiven/aiven-extras/security/advisories/GHSA-7r4w-fw4h-67gp https://security.netapp.com/advisory/ntap-20230616-0006 • CWE-20: Improper Input Validation CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
