Description:
Three vulnerabilities have been reported in Drupal, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, and by malicious users to potentially compromise a vulnerable system.
1) Input passed to unspecified parameters is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerability has been reported in version 4.6.6 and prior, and in version 4.7.0 and prior.
2) Missing access restrictions to the "files" directory in certain configurations can be exploited by users with upload rights and with permissions to modify stories, to upload files with multiple file name extensions and executing them.
Successful exploitation requires that the "mod_mime" module is installed in Apache, and that a " .htaccess" file has not been used to restrict access to the directory.
The vulnerability has been reported in all versions prior to 4.6.8, and in all versions prior to 4.7.2.
3) Input passed to unspecified parameter in the upload.module isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability has been reported in all versions prior to 4.7.2.
Solution:
Update to version 4.6.8 or 4.7.2, or apply patches.
