MySQL debian.cnf Plaintext Credential Disclosure

low Nessus Plugin ID 71862

Language:

Synopsis

The remote database server may be affected by an information disclosure vulnerability.

Description

The version of MySQL installed on the remote host is 5.5.x prior to 5.5.33. It is, therefore, potentially affected by a race condition in the post-installation script of the MySQL server package (mysql-server-5.5.postinst) that creates the configuration file '/etc/mysql/debian.cnf' with world-readable permissions before restricting the permissions. This allows local users to read the file and obtain credentials for the privileged 'debian-sys-maint' user.

Solution

Upgrade the MySQL server package to 5.5.33 or later on Debian / 5.5.32 or later on Ubuntu.
