Secunia

Some vulnerabilities have been reported in the Go - url redirects module for Drupal, which can be exploited by malicious users and potentially malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, and compromise a vulnerable system.

1) Improper use of the PCRE regular expression engine can be exploited to inject and execute arbitrary PHP code.

Successful exploitation requires access to the input filter provided by the module

2) Certain unspecified user supplied input is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.

3) Due to certain unspecified errors and due to the fact that the application allows users to perform certain actions via HTTP requests without performing any validation checks to verify the requests, users may be able to add redirects or reset redirect counters.

Solution
