CVE-2007-3278: PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Lin...

Security readout for executives and security teams

This vulnerability affects PostgreSQL configurations that combine local trust authentication with the dblink library. In that setup, a remote attacker may be able to make the database connect as localhost and run SQL as accounts they should not control. Business risk is highest where old PostgreSQL systems remain internet-reachable or trusted by applications. Exposure appears configuration-dependent: PostgreSQL 8.1 and probably later versions, dblink installed, local trust authentication enabled, and an attacker able to invoke dblink through SQL access. Systems without dblink or without trust authentication are not shown as affected by the supplied sources. Prioritize investigation if legacy PostgreSQL supports important business systems. The issue can allow unauthorized SQL execution, but only under specific configuration conditions, so urgency depends on whether dblink and local trust authentication are present. Mitigation focus: Review current PostgreSQL vendor or distribution guidance for supported fixes.; Disable local trust authentication where it is not strictly required.; Remove or restrict dblink if applications do not need it..
