Advisory Content : -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hardened-PHP Project www.hardened-php.net -= Security Advisory =- Advisory: PHP Cross Site Scripting (XSS) Vulnerability in phpinfo() Release Date: 2005/10/31 Last Modified: 2005/10/31 Author: Stefan Esser [sesser (at) hardened-php (dot) net [email concealed]] Application: PHP4 <= 4.4.0 PHP5 <= 5.0.5 Severity: A Cross Site Scripting (XSS) Vulnerability in phpinfo() could f.e. lead to cookie data exposure if an info script is left on a production server. Risk: Low Vendor Status: Vendor has released a bugfixed PHP 4 version References: http://www.hardened-php.net/advisory_182005.77.html Overview: PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. During the development of the Hardening-Patch which adds security hardening features to the PHP codebase, several vulnerabilities within PHP were discovered. This advisory describes one of these flaws concerning a weakness in the phpinfo() function, which allows Cross Site Scripting (XSS). Details: The phpinfo() function outputs a large amount of information about the current state of PHP. This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options and request variables, HTTP headers, and the PHP License. Because phpinfo() leaks a lot of information to the viewer it is not recommended to leave a script executing phpinfo() on a production server. However in reality phpinfo() scripts are left open on a lot of servers. While this is already bad enough, there is also a problem when request variables of a certain form are displayed. With a properly crafted URL, that contains a stacked array assignment it is f.e. possible to inject HTML code into the output of phpinfo(), which could result in the leakage of domain cookies (f.e. session identifiers). Proof of Concept: The Hardened-PHP project is not going to release exploits for any of these vulnerabilities to the public. Recommendation: It is strongly recommended to never leave phpinfo() scripts on production servers, additionally it is recommended to upgrade to the new PHP-Releases as soon as possible, because it also fixes a few vulnerabilities, that are rated critical. Finally we always recommend to run PHP with the Hardening-Patch applied.
