Description

MySQL contains a flaw that may allow a malicious user to authenticate with the database without a password. The issue is triggered when a 4.1 protocol request occurs with a zero length password. It is possible that the flaw may allow arbitrary SQL command execution resulting in a loss of confidentiality and integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Confidentiality, Loss of Integrity

Solution

Upgrade to version 4.1.3 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): rename the 'root' account and apply host based login restrictions.

Note that the 4.0 series of the MySQL server is not affected and does not require an upgrade.
