Drupal — система управления контентом с открытым исходным кодом. На Drupal работает более миллиона сайтов — от личных блогов до сайтов компаний, политических партий и государственных организаций.

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.

The _json_decode function in plugins/context_reaction_block.inc in the Context module 6.x-2.x before 6.x-3.2 and 7.x-3.x before 7.x-3.0 for Drupal, when using a version of PHP that does not support the json_decode function, allows remote attackers to execute arbitrary PHP code via unspecified vectors related to Ajax operations, possibly involving eval injection.

The json rendering functionality in the Context module 6.x-2.x before 6.x-3.2 and 7.x-3.x before 7.x-3.0 for Drupal uses Drupal's token scheme to restrict access to blocks, which makes it easier for remote authenticated users to guess the access token for a block by leveraging the token from a block to which the user has access.

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.

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.

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.
