Description

PostgreSQL before 9.5.x before 9.5.2 does not properly maintain row-security status in cached plans, which might allow attackers to bypass intended access restrictions by leveraging a session that performs queries as more than one role.

Solution(s)

  • postgres-upgrade-9_5_2

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
