TITLE:
Drupal Go - url redirects Module Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA36503
VERIFY ADVISORY:
http://secunia.com/advisories/36503/
DESCRIPTION:
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:
Update to version 5.x-1.4 or 6.x-1.1.
