Remote code execution vulnerability when run as CGI
A vulnerability was discovered where a user can execute a remote code execution attack against a server when phpMyAdmin is being run as a CGI application. Under certain server configurations, a user can pass a query string which is executed as a command-line argument by the file generator_plugin.sh.
Updated 2016-12-08: Added fix for prohibiting the execution altogether.
We consider this vulnerability to be critical.
The file `/libraries/plugins/transformations/generator_plugin.sh` may be removed. Under certain server configurations, it may be sufficient to remove execute permissions for this file.
All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected
Upgrade to phpMyAdmin 4.6.4, 4.4.15.8, 4.0.10.17, or newer, or apply patch listed below.
