phpMyAdmin < 2.5.6-rc1: possible attack against export.php — GLSA 200402-05

A vulnerability in phpMyAdmin which was not properly verifying user generated input could lead to a directory traversal attack.

Affected packages

dev-db/phpmyadmin on all architectures
Affected versions <= 2.5.5_p1
Unaffected versions >= 2.5.6_rc1


phpMyAdmin is a tool written in PHP intended to handle the administration of MySQL databased over the Web.


One component of the phpMyAdmin software package (export.php) does not properly verify input that is passed to it from a remote user. Since the input is used to include other files, it is possible to launch a directory traversal attack.


Private information could be gleaned from the remote server if an attacker uses a malformed URL such as[existing_file]

In this scenario, the script does not sanitize the "what" argument passed to it, allowing directory traversal attacks to take place, disclosing the contents of files if the file is readable as the web-server user.


The workaround is to either patch the export.php file using the referenced CVS patch or upgrade the software via Portage.


Users are encouraged to upgrade to phpMyAdmin-2.5.6_rc1:

 # emerge sync
 # emerge -pv ">=dev-db/phpmyadmin-2.5.6_rc1"
 # emerge ">=dev-db/phpmyadmin-2.5.6_rc1"
 # emerge clean
