Описание
Type confusion in PostgreSQL module "refint" allows an object creator to execute arbitrary code as the operating system user running the database. The fix for this emerged as a non-security bug report, and the fix appear in the git repository with subject "refint: Remove plan cache.", without a CVE number. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
A flaw was found in PostgreSQL. A type confusion vulnerability in the 'refint' module allows an object creator to execute arbitrary code as the operating system user running the database. This could lead to a complete compromise of the database server.
Отчет
An Important-rated type confusion vulnerability in PostgreSQL's refint module allows an authenticated user with object creation privileges to execute arbitrary code. Successful exploitation results in a complete compromise of the database server, as the code executes under the context of the database's operating system user."
Меры по смягчению последствий
To mitigate this vulnerability, administrators should avoid installing the refint module and remove it if it is currently deployed by executing DROP EXTENSION refint; as a database superuser. Additionally, enforcing the principle of least privilege by revoking CREATE permissions on databases from untrusted users prevents them from creating the malicious objects necessary to exploit this flaw.
