PHPlist, http://www.phplist.com is a popular open source newsletter application written in PHP.
Recently a file injection vulnerability has been discovered allowing remote attackers to issue arbitrary commands on the hosted machine, as the webserver user.
The issue has been resolved in the latest release, version 2.6.4 available at http://www.phplist.com/files
Versions affected: any version up to 2.6.2
If Apache is used, the following .htacces file in the "admin" directory will patch the problem for any affected version, provided the server permissions allow overriding the relevant directives
<FilesMatch "\.(php|inc)$"> Order allow,deny deny from all </FilesMatch> <FilesMatch "index.php$"> Order allow,deny allow from all </FilesMatch>
