CRLF injection vulnerability in the drupal_set_header function in Drupal 6.x before 6.38, when used with PHP before 5.1.2, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks by leveraging a module that allows user-submitted data to appear in HTTP headers.
Open redirect vulnerability in the drupal_goto function in Drupal 6.x before 6.38, when used with PHP before 5.4.7, allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a double-encoded URL in the "destination" parameter.
The Form API in Drupal 6.x before 6.38 ignores access restrictions on submit buttons, which might allow remote attackers to bypass intended access restrictions by leveraging permission to submit a form with a button that has "#access" set to FALSE in the server-side form definition.
Drupal 6.x before 6.38, 7.x before 7.43, and 8.x before 8.0.4 might allow remote attackers to conduct open redirect attacks by leveraging (1) custom code or (2) a form shown on a 404 error page, related to path manipulation.
The XML-RPC system in Drupal 6.x before 6.38 and 7.x before 7.43 might make it easier for remote attackers to conduct brute-force attacks via a large number of calls made at once to the same method.
The Form API in Drupal 6.x before 6.37 and 7.x before 7.39 does not properly validate the form token, which allows remote attackers to conduct CSRF attacks that upload files in a different user's account via vectors related to "file upload value callbacks."
Cross-site scripting (XSS) vulnerability in the Autocomplete system in Drupal 6.x before 6.37 and 7.x before 7.39 allows remote attackers to inject arbitrary web script or HTML via a crafted URL, related to uploading files.
Cross-site request forgery (CSRF) vulnerability in the Content Lock module for Drupal allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.
The request_path function in includes/bootstrap.inc in Drupal 7.14 and earlier allows remote attackers to obtain sensitive information via the q[] parameter to index.php, which reveals the installation path in an error message.
