Vulnerability Details

PostgreSQL 10.x < 10.14, 11.x < 11.9, 12.x < 12.4 Search Path Vulnerability (Windows)

Published: 2020-10-07 07:03:40
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:H/Au:S/C:P/I:P/A:P

Detection Type:
Remote Banner

Solution Type:
Vendor Patch

Summary:
PostgreSQL is prone to an uncontrolled search path element vulnerability in logical replication.

Detection Method:
Checks if a vulnerable version is present on the target host.

Impact:
The PostgreSQL search_path setting determines schemas searched for tables, functions, operators, etc. The CVE-2018-1058 fix caused most PostgreSQL-provided client applications to sanitize search_path, but logical replication continued to leave search_path unchanged. Users of a replication publisher or subscriber database can create objects in the public schema and harness them to execute arbitrary SQL functions under the identity running replication, often a superuser. Installations having adopted a documented secure schema usage pattern are not vulnerable.

Affected Versions:
PostgreSQL versions 10.x prior to 10.14, 11.x prior to 11.9 and 12.x prior to 12.4.

Recommendations:
Update to version 10.14, 11.9, 12.4 or later.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
