phpMyFAQ Generates an Error Message Containing Sensitive Information if database server is not available

Summary

Exposure of database (ie postgreSQL) server's credential when connection to DB fails.

Details

Exposed database credentials upon misconfig/DoS @ permalink: https://github.com/thorsten/phpMyFAQ/blob/main/phpmyfaq/src/phpMyFAQ/Setup/Installer.php#L694

PoC

When postgreSQL server is unreachable, an error would be thrown exposing the credentials of the database. For instance, when "http://:8080/setup/index.php" is hit when the database instance/server is down, then credentials are exposed, for instance:

( ! ) Warning: pg_connect(): Unable to connect to PostgreSQL server: connection to server at "127.0.0.1", port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? in /var/www/html/src/phpMyFAQ/Database/Pgsql.php on line 78 Call Stack # Time Memory Function Location 1 0.0404 453880 {main}( ) .../index.php:0 2 1.1341 610016 phpMyFAQ\Setup\Installer->startInstall( $setup = ??? ) .../index.php:471 3 1.2113 611544 phpMyFAQ\Database\Pgsql->connect( $host = '127.0.0.1', $user = 'cvecve', $password = '<redacted>', $database = 'cvecve', $port = 5432 ) .../Installer.php:694 4 1.2113 611864 pg_connect( $connection_string = 'host=127.0.0.1 port=5432 dbname=cvecve user=cvecve password=<redacted>' ) .../Pgsql.php:78 ( ! ) Fatal error: Uncaught TypeError: Cannot assign false to property phpMyFAQ\Database\Pgsql::$conn of type ?PgSql\Connection in /var/www/html/src/phpMyFAQ/Database/Pgsql.php on line 78 ( ! ) TypeError: Cannot assign false to property phpMyFAQ\Database\Pgsql::$conn of type ?PgSql\Connection in /var/www/html/src/phpMyFAQ/Database/Pgsql.php on line 78 Call Stack # Time Memory Function Location 1 0.0404 453880 {main}( ) .../index.php:0 2 1.1341 610016 phpMyFAQ\Setup\Installer->startInstall( $setup = ??? ) .../index.php:471 3 1.2113 611544 phpMyFAQ\Database\Pgsql->connect( $host = '127.0.0.1', $user = 'cvecve', $password = '<redacted>', $database = 'cvecve', $port = 5432 ) .../Installer.php:694

A way to force this would be to perform a denial of service on the database instance/server. When the db connection is refused, the credentials would show. The remote attacker can then use that to gain full control on the database.

Impact

This vulnerability exposes the credentials of the database and grants a remote attacker full control over the database.
