TITLE:
Drupal Script Insertion and Information Disclosure
SECUNIA ADVISORY ID:
SA34950
VERIFY ADVISORY:
http://secunia.com/advisories/34950/
DESCRIPTION:
Some vulnerabilities have been reported in Drupal, which can be
exploited by malicious people to conduct script insertion attacks or
to disclose potentially sensitive information.
1) User provided input is not properly sanitised before being used.
This can be exploited to insert arbitrary HTML and script code, which
will be executed in a user's browser session in context of an affected
site when the malicious data is viewed and interpreted as UTF-7.
Successful exploitation requires the ability to post content.
2) An unspecified error can be exploited to disclose information
about form submissions when a user is tricked into submitting a form
after following a specially crafted link to the site. This can
further be exploited to conduct e.g. cross-site request forgery
attacks.
The vulnerabilities are reported in Drupal 5.x prior to version 5.17
and Drupal 6.x prior to version 6.11.
SOLUTION:
Update to Drupal 6.11 or Drupal 5.17, or apply the patches.
