Secunia

Multiple vulnerabilities have been reported and discovered in Maian Greetings, which can be exploited by malicious users to compromise a vulnerable system and by malicious people to conduct cross-site scripting, SQL injection attacks, and to bypass certain security restrictions.

1) Input passed to the "keywords" parameter in index.php (when "cmd" is set to "search") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "msg_script" and "msc_script2" parameter in admin/inc/header.php is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) A vulnerability is caused due to improper access restriction in the admin/index.php script. This can be exploited to bypass the authentication mechanism and gain access to the administration section by setting the "mecard_admin_cookie" cookie.

4) Input passed via the "Upload Your Own Image" form to the index.php script (when "cmd" is set to "ecard" and "action" is set to "upload") is not properly verified before being used to store files to the images/uploads folder. This can be exploited to execute arbitrary PHP code by uploading a PHP file with multiple extensions.

Successful exploitation requires that Apache is not configured to handle the mime-type for uploadable media files.

Vulnerabilities #1, #2, and #3 are reported in version 2.1 and vulnerability #4 is confirmed in version 2.1. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
