Security Bulletin: A security vulnerability in PostgreSQL affects IBM Cloud Pak for Multicloud Management.

Vulnerability Details

CVEID:   CVE-2020-14349
DESCRIPTION:   PostgreSQL could allow a remote authenticated attacker to execute arbitrary command on the system, caused by improper sanitization of search_path during logical replication. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary SQL command in the context of the user used for replication.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/187185 for the current score.

CVEID:   CVE-2020-14350
DESCRIPTION:   PostgreSQL could allow a remote authenticated attacker to execute arbitrary code on the system, caused by the failure to use search_path safely in their installation script. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary script.
CVSS Base score: 8.8

CVEID:   CVE-2020-25696
DESCRIPTION:   PostgreSQL could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the psql interactive terminal. If an interactive psql session uses \gset when querying a compromised server, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192321 for the current score.

CVEID:   CVE-2020-25695
DESCRIPTION:   PostgreSQL could allow a remote authenticated attacker to gain elevated privileges on the system, caused by a flaw when creating non-temporary objects in at least one schema. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary SQL functions under the identity of a superuser.
CVSS Base score: 8.8

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2020-25694
DESCRIPTION:   PostgreSQL could allow a remote attacker to obtain sensitive information, caused by the use of clear-text transmissions when reusing the basic connection parameters while dropping security-relevant parameters. By using man-in-the-middle attack techniques, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
