phpMyAdmin: Multiple vulnerabilities

Background

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

Description

Stefan Esser from Hardened-PHP reported about multiple vulnerabilties found in phpMyAdmin. The $GLOBALS variable allows modifying the global variable import_blacklist to open phpMyAdmin to local and remote file inclusion, depending on your PHP version (CVE-2005-4079, PMASA-2005-9). Furthermore, it is also possible to conduct an XSS attack via the $HTTP_HOST variable and a local and remote file inclusion because the contents of the variable are under total control of the attacker (CVE-2005-3665, PMASA-2005-8).

Impact

A remote attacker may exploit these vulnerabilities by sending malicious requests, causing the execution of arbitrary code with the rights of the user running the web server. The cross-site scripting issues allow a remote attacker to inject and execute malicious script code or to steal cookie-based authentication credentials, potentially allowing unauthorized access to phpMyAdmin.

Workaround

There is no known workaround at this time.

Resolution

All phpMyAdmin users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/phpmyadmin-2.7.0_p1"
