ESA-2014-160: RSA® Adaptive Authentication (On-Premise) Authentication Bypass Vulnerability

EMC Identifier: ESA-2014-160

CVE Identifier: CVE-2014-4631

Severity Rating: CVSS: 6.8 (AV:N/AC:M/Au:N/C:P/I:P/A:P)
 
Affected Products:

RSA Adaptive Authentication (On-Premise) 6.0.2.1 to 7.1 P3 (inclusive)
RSA Adaptive Authentication Integration Adapters 1.x and 2.x
 
Unaffected Products:

RSA Adaptive Authentication (Hosted) all versions

Summary: 

RSA Adaptive Authentication (On-Premise) 6.0.2.1 to 7.1 P3 (inclusive) are potentially vulnerable to an authentication bypass vulnerability, if a device binding request is sent in an AAOP challenge SOAP call.
 
Details:

When requesting device binding in a Challenge SOAP call, permanent device binding takes place regardless of the success or failure of the authentication. This could potentially lead to an authentication bypass scenario.
 
In RSA Adaptive Authentication Integration Adapters, a device binding request is sent in the Challenge SOAP call for Out-of-Band Phone (Authentify) functionality only.
 
Recommendation:

RSA Adaptive Authentication customers who submit device binding request within a Challenge call or are using the RSA Adaptive Authentication Integration Adapters with Out-of-Band Phone (Authentify) functionality are recommended to upgrade to RSA Adaptive Authentication On-Premise 7.1 P4, which contain fixes to resolve this issue.
 
In order to determine if their Adaptive Authentication deployment is vulnerable to this issue, customers need to identify if Integration Adapters are used with Out-of-Band Phone (Authentify) functionality or, if using the API directly, need to review their implementation to determine if device binding is requested as part of the Challenge SOAP call.
 
For any customers impacted by this implementation issue, RSA recommends upgrading to RSA Adaptive Authentication On-Premise 7.1 P4 in which permanent device binding is not established unless successful authentication occurs in an Authentication or a QueryAuthStatus SOAP call.
 
Integration Adapter customers must upgrade their Adaptive Authentication installation to RSA Adaptive Authentication On-Premise 7.1 P4 to resolve this issue. Adaptive Authentication customers who are unable to upgrade to RSA AAOP 7.1 P4, but have determined they are vulnerable to this issue, may alternatively alter their API usage by moving the DeviceManagementRequest from the Challenge to the Authenticate or QueryAuthStatus call, depending on Challenge mechanism used, which will also ensure the device binding only occurs upon successful authentication.
