PMASA-2013-2

Announcement-ID: PMASA-2013-2

Date: 2013-04-24
Summary

Remote code execution via preg_replace().
Description

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.
Severity

We consider this vulnerability to be serious.
Mitigation factor

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.
Affected Versions

Versions 3.5.x and 4.0.0 (before -rc3) are affected.
Solution

For 3.5.x, upgrade to phpMyAdmin 3.5.8 or newer; for 4.0.x, upgrade to 
4.0.0-rc3 or newer. You can also apply the patches listed below.

PMASA-2013-3

Announcement-ID: PMASA-2013-3

Date: 2013-04-24
Summary

Locally Saved SQL Dump File Multiple File Extension Remote Code Execution.
Description

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.
Severity

We consider this vulnerability to be serious.
Mitigation factor

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.
Affected Versions

Versions 3.5.x and 4.0.0 (before -rc3) are affected.
Solution

For 3.5.x, upgrade to phpMyAdmin 3.5.8 or newer; for 4.0.x, upgrade to 
4.0.0-rc3 or newer. You can also apply the patches listed below.

PMASA-2013-4

Announcement-ID: PMASA-2013-4

Date: 2013-04-24
Summary

Local file inclusion vulnerability.
Description

In the Export feature, a parameter specifying the export type was not 
correctly validated, opening the door to a local file inclusion attack.
Severity

We consider this vulnerability to be serious.
Mitigation factor

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.
Affected Versions

phpMyAdmin versions 4.x (prior to 4.0.0-rc3).
Solution

Upgrade to phpMyAdmin 4.0.0-rc3 or newer.

PMASA-2013-5

Announcement-ID: PMASA-2013-5

Date: 2013-04-24
Summary

Global variables overwrite in "export.php".
Description

The export script generates global variables from those present in the $_POST 
superglobal. This may lead to other exploits in the export script.
Severity

We consider this vulnerability to be serious.
Mitigation factor

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.
Affected Versions

phpMyAdmin versions 4.x (prior to 4.0.0-rc3).
Solution

Upgrade to phpMyAdmin 4.0.0-rc3 or newer.
