CVE-2010-3686

The OpenID module in Drupal 6.x before 6.18, and the OpenID module 5.x before 5.x-1.4 for Drupal, violates the OpenID 2.0 protocol by not ensuring that fields are signed, which allows remote attackers to bypass authentication by leveraging an assertion from an OpenID provider.

Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2010-3686.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.

Access Complexity (AC): Low. No special conditions beyond the attacker-controlled steps are required.
Authentication (Au): None. The attacker does not need to authenticate.
Confidentiality Impact (C): None. There is no impact to this security property.
Integrity Impact (I): Partial. There is a limited impact to this security property.
Availability Impact (A): None. There is no impact to this security property.
