CVE-2018-10925

Disclosure Date: August 09, 2018 •
CVE-2018-10925 CVSS v3 Base Score: 8.1
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with “INSERT … ON CONFLICT DO UPDATE”. An attacker with “CREATE TABLE” privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain “INSERT” and limited “UPDATE” privileges to a particular table, they could exploit this to update other columns in the same table.
