Описание
Type confusion with PostgreSQL "internal" data type arguments allows any user to execute arbitrary code as the operating system user running the database, via calls to functions with that argument type. Type "internal" represents a class of mutually-incompatible data structures not intended for access from SQL. The system intended to prevent such function calls, but this prevention had gaps. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
A type confusion vulnerability in PostgreSQL allows any user to execute arbitrary code as the database's operating system user by calling functions with mishandled "internal" data type arguments.
Отчет
This is an Important vulnerability where any authenticated PostgreSQL user can achieve arbitrary code execution as the operating system user running the database. This type confusion flaw bypasses intended security boundaries for 'internal' data types, leading to a significant privilege escalation and potential compromise of the entire database server.
Меры по смягчению последствий
Restrict PostgreSQL to trusted hosts and bind only the required interfaces; use pg_hba.conf so only trusted clients can reach the port. Do not grant CONNECT (or any SQL login) to untrusted roles —any session can trigger this.
