Insufficient output sanitizing when generating configuration file.
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 ability to save files on server, this can allow unauthenticated users to execute arbitrary PHP code. This issue is on different parameters than PMASA-2009-3 and it was missed out of our radar because it was not existing in 2.11.x branch.
We consider this vulnerability to be critical.
Additional steps from administrator are required to actually exploit this issue (web server writable config directory has to be created).
For 2.11.x: versions are not affected.
For 3.x: versions before 188.8.131.52.
Upgrade to phpMyAdmin 184.108.40.206 or apply patches listed below.
