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

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.
