PMASA-2010-4

Announcement-ID: PMASA-2010-4

Date: 2010-08-20

Summary

Insufficient output sanitizing when generating configuration file.

Description

The setup script used to generate configuration can be fooled using a crafted POST request to include arbitrary PHP code in generated configuration file. Combined with the ability to save files on the server, this can allow unauthenticated users to execute arbitrary PHP code.

Severity

We consider this vulnerability to be critical.

Mitigation factor

Additional steps from administrator are required to actually exploit this issue (a web server writable config directory has to be created).

Affected Versions

For 2.11.x: versions before 2.11.10.1.

Unaffected Versions

Branch 3.x is not affected by this.

Solution

Upgrade to phpMyAdmin 2.11.10.1 or apply the patch listed below.
