ESA-2013-029: RSA SecurID Sensitive Information Disclosure Vulnerability
EMC Identifier: ESA-2013-029
CVE Identifier: CVE-2013-0941
Severity Rating: CVSS v2 Base Score: 6.8 (AV:L/AC:L/Au:S/C:C/I:C/A:C)
Affected Products:
RSA Authentication API versions prior to 8.1 SP1
RSA Web Agent for Apache Web Server versions prior to 5.3.5
RSA Web Agent for IIS versions prior to 5.3.5
RSA PAM Agent versions prior to 7.0
RSA Agent for Microsoft Windows versions prior to 6.1.4
Unaffected Products:
RSA Authentication API versions 8.1 SP1 and later
RSA Web Agent for Apache Web Server versions 5.3.5 and later
RSA Web Agent for IIS versions 5.3.5 and later
RSA PAM Agent versions 7.0 and later
RSA Agent for Microsoft Windows version 6.1.4
RSA EAP Client 7.0 and later
RSA Authentication Agent for Microsoft Windows 7.1
RSA SecurID Authentication Agent 7.1 for Web for Apache Web Server
RSA SecurID Authentication Agent 7.1 for Web for Internet Information Services
Summary:
The node secret in affected products was stored using an encryption key and
encryption algorithm that is no longer considered effective by RSA standards.
An attacker could potentially exploit this to eavesdrop on or modify network
communications.
Details:
The node secret is a symmetric encryption key that RSA Authentication Manager
and RSA Authentication Agents use to protect network communications. In
affected products, the node secret is encrypted and stored on the agent host
using a dated encryption algorithm and weak key.
All agent software which leverages the RSA SecurID Authentication API has been
updated to use stronger encryption and stronger keys.
Note: All agent software, whether shipped by RSA or one of its RSA Secured
Partners, which leverage the RADIUS Protocol is NOT affected by this issue.

Following is the recommendation for action to be taken to obtain this security
fix:
RSA Authentication Agent for Microsoft Windows 6.1.3
Recommendation: Please upgrade to RSA Authentication Agent for Microsoft
Windows 6.1.4
