Drupal 6.x before 6.31 and 7.x before 7.27 does not properly isolate the cached data of different anonymous users, which allows remote anonymous users to obtain sensitive interim form input information in opportunistic situations via unspecified vectors.

Updated drupal packages fix security vulnerabilities :

An information disclosure vulnerability was discovered in Drupal before 7.27. When pages are cached for anonymous users, form state may leak between anonymous users. Sensitive or private information recorded for one anonymous user could thus be disclosed to other users interacting with the same form at the same time (CVE-2014-2983).

Multiple security issues in Drupal before 7.29, including a denial of service issue, an access bypass issue in the File module, and multiple cross-site scripting issues (CVE-2014-5019, CVE-2014-5020, CVE-2014-5021, CVE-2014-5022).

A denial of service issue exists in Drupal before 7.31, due to XML entity expansion in a publicly accessible XML-RPC endpoint.

A SQL Injection issue exists in Drupal before 7.32 due to the way the Drupal core handles prepared statements. A malicious user can inject arbitrary SQL queries, and thereby completely control the Drupal site.
This vulnerability can be exploited by remote attackers without any kind of authentication required (CVE-2014-3704).

Aaron Averill discovered that a specially crafted request can give a user access to another user's session, allowing an attacker to hijack a random session (CVE-2014-9015).

Michael Cullum, Javier Nieto and Andres Rojas Guerrero discovered that the password hashing API allows an attacker to send specially crafted requests resulting in CPU and memory exhaustion. This may lead to the site becoming unavailable or unresponsive (denial of service) (CVE-2014-9016). anonymous users (CVE-2014-9016).

Password reset URLs can be forged under certain circumstances, allowing an attacker to gain access to another user's account without knowing the account's password (CVE-2015-2559).

Under certain circumstances, malicious users can construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks. In addition, several URL-related API functions in Drupal 6 and 7 can be tricked into passing through external URLs when not intending to, potentially leading to additional open redirect vulnerabilities (CVE-2015-2749, CVE-2015-2750).

The drupal package has been updated to version 7.35 to fix this issue and other bugs. See the upstream advisory and release notes for more details.

An information disclosure vulnerability was discovered in Drupal, a fully-featured content management framework. When pages are cached for anonymous users, form state may leak between anonymous users.
Sensitive or private information recorded for one anonymous user could thus be disclosed to other users interacting with the same form at the same time.

This security update introduces small API changes, see the upstream advisory at drupal.org/SA-CORE-2014-002 for further information.

The remote web server is running a version of Drupal that is 7.x prior to 7.27. It is, therefore, affected by an error related to the HTML form API and the caching of pages for different anonymous users, which could allow sensitive information to be disclosed. Note that Drupal core does not expose any such HTML forms by default.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
