PostgreSQL 11.x < 11.11 / 12.x < 12.6 / 13.x < 13.2 Multiple Vulnerabilities

medium Nessus Plugin ID 148419

Language:

Synopsis

The remote database server is affected by multiple vulnerabilities

Description

The version of PostgreSQL installed on the remote host is 11 prior to 11.11, 12 prior to 12.6, or 13 prior to 13.2. As such, it is potentially affected by multiple vulnerabilities :

 - An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11.
 A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.
 (CVE-2021-3393)

 - A flaw was found in PostgreSQL in versions before 13.2, before 12.6, before 11.11. This flaw allows a user with SELECT privilege on one column to craft a special query that returns all columns of the table.
 The highest threat from this vulnerability is to confidentiality (CVE-2021-20229)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PostgreSQL 11.11 / 12.6 / 13.2 or later
