Insufficient output sanitizing when generating configuration file.
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.
We consider this vulnerability to be critical.
Additional steps from administrator are required to actually exploit this issue (a web server writable config directory has to be created).
For 2.11.x: versions before 220.127.116.11.
Branch 3.x is not affected by this.
Upgrade to phpMyAdmin 18.104.22.168 or apply the patch listed below.
