Severity: Medium
Vulnerability Published: 2013-04-24
Patch Published: 2013-04-24
CVE [?]: CVE-2013-3238, CVE-2013-3239
CPE [?]: cpe:/o:freebsd:freebsd, p-cpe:/a:freebsd:freebsd:phpMyAdmin

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The phpMyAdmin development team reports :

In some PHP versions, the preg_replace() function can be tricked into executing arbitrary PHP code on the server. This is done by passing a crafted argument as the regular expression, containing a null byte. phpMyAdmin does not correctly sanitize an argument passed to preg_replace() when using the 'Replace table prefix' feature, opening the way to this vulnerability..

This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users to access the required form.

phpMyAdmin can be configured to save an export file on the web server, via its SaveDir directive. With this in place, it's possible, either via a crafted filename template or a crafted table name, to save a double extension file like foobar.php.sql. In turn, an Apache webserver on which there is no definition for the MIME type 'sql' (the default) will treat this saved file as a '.php' script, leading to remote code execution.

This vulnerability can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users to access the required form. Moreover, the SaveDir directive is empty by default, so a default configuration is not vulnerable. The $cfg['SaveDir'] directive must be configured, and the server must be running Apache with mod_mime to be exploitable.

Solution

Update the affected package.
