CVE-2011-2741
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedEMC RSA Adaptive Authentication On-Premise (AAOP) 6.0.2.1 SP1 Patch 2, SP1 Patch 3, SP2, SP2 Patch 1, and SP3 does not properly implement Device Recovery and Device Identification, which might allow remote attackers to bypass intended security restrictions on a (1) previously non-registered device or (2) registered device by sending unspecified "data elements."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceEMC RSA Adaptive Authentication On-Premise fails to properly validate device identity during the Device Recovery and Device Identification processes. This allows remote attackers to bypass authentication restrictions by sending crafted data elements that impersonate either unregistered devices to gain access or registered devices to escalate privileges. The vulnerability affects multiple patch levels of version 6.0.2.1.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm RSA Adaptive Authentication On-Premise is installedLocate the RSA Adaptive Authentication On-Premise installation directory or check system inventory for this productAffected if The product is installed and running
-
Verify the installed version is 6.0.2.1Check the product version using the vendor-provided version command, about screen, or version file within the installation directoryAffected if The installed version equals exactly 6.0.2.1
-
Confirm Device Recovery feature is in useReview the product configuration or deployment documentation to determine if the Device Recovery process is enabledAffected if Device Recovery functionality is configured or active in the environment
-
Confirm Device Identification feature is in useReview the product configuration or deployment documentation to determine if the Device Identification process is enabledAffected if Device Identification functionality is configured or active in the environment
If RSA Adaptive Authentication On-Premise version 6.0.2.1 is installed with Device Recovery or Device Identification features enabled, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches from EMC/RSA for this vulnerability. If patches are unavailable, implement additional authentication layers (e.g., multi-factor authentication, risk-based authentication) to compensate for the flawed device fingerprinting, and review device registration logs for suspicious activity.
