The form API in Drupal 6.x before 6.29 and 7.x before 7.24, when used with unspecified third-party modules, performs form validation even when CSRF validation has failed, which might allow remote attackers to trigger application-specific impacts such as arbitrary code execution via application-specific vectors.
Drupal 6.x before 6.29 and 7.x before 7.24 uses the PHP mt_rand function to generate random numbers, which uses predictable seeds and allows remote attackers to predict security strings and bypass intended restrictions via a brute force attack.
Open redirect vulnerability in the Overlay module in Drupal 7.x before 7.24 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.
Drupal 6.x before 6.23 and 7.x before 7.11 does not verify that Attribute Exchange (AX) information is signed, which allows remote attackers to modify potentially sensitive AX information without detection via a man-in-the-middle (MITM) attack.
Cross-site request forgery (CSRF) vulnerability in the Aggregator module in Drupal 6.x before 6.23 and 7.x before 7.11 allows remote attackers to hijack the authentication of unspecified victims for requests that update feeds and possibly cause a denial of service (loss of updates due to rate limit) via unspecified vectors.
The File module in Drupal 7.x before 7.11, when using unspecified field access modules, allows remote authenticated users to read arbitrary private files that are associated with restricted fields via unspecified vectors.
The printer friendly version functionality in the Book module in Drupal 6.x before 6.28 and 7.x before 7.19 does not properly restrict access to node that are part of a book outline, which allows remote authenticated users with the "access printer-friendly version" permission to read node titles and possibly node content via unspecified vectors.
The Image module in Drupal 7.x before 7.19, when a private file system is used, does not properly restrict access to derivative images, which allows remote attackers to read derivative images of otherwise restricted images via unspecified vectors.
The Image module in Drupal 7.x before 7.20 allows remote attackers to cause a denial of service (CPU and disk space consumption) via a large number of new derivative requests.
Cross-site request forgery (CSRF) vulnerability in the RESTful Web Services (restws) module 7.x-1.x before 7.x-1.2 and 7.x-2.x before 7.x-2.0-alpha4 for Drupal allows remote attackers to hijack the authentication of arbitrary users via unknown vectors.
