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.
