Description


Some vulnerabilities have been reported in the OpenID module for Drupal, which can be exploited by malicious users to hijack accounts and by malicious people to conduct cross-site request forgery attacks.

1) The OpenID module allows users to perform certain actions via HTTP requests without performing any validation checks to verify the requests. This can be exploited to e.g. add OpenID identities to existing accounts.

2) An unspecified error within the OpenID Authentication 2.0 implementation can be exploited to hijack another user's account if the same OpenID 2.0 provider is used.

This is related to vulnerabilities #1 and #2 in:
SA36781

The vulnerabilities are reported in versions prior to 5.x-1.3.


Solution:
Update to version 5.x-1.3.
