CVE-2014-8027
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 · uneditedThe RBAC component in Cisco Secure Access Control System (ACS) allows remote authenticated users to obtain Network Device Administrator privileges for Create, Delete, Read, and Update operations via crafted HTTP requests, aka Bug ID CSCuq79034.
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 confidenceThe RBAC (Role-Based Access Control) component in Cisco Secure Access Control System (ACS) contains a privilege escalation vulnerability where remote authenticated users can obtain Network Device Administrator privileges for Create, Delete, Read, and Update operations through crafted HTTP requests. This allows unauthorized users to bypass their assigned role permissions and perform administrative-level operations.

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.
-
Identify Cisco ACS installationLocate the Cisco Secure ACS application in your environment - check for the ACS web interface, running services, or installation directories on Windows or Linux hostsAffected if Cisco Secure Access Control System is deployed in the environment
-
Determine ACS versionAccess the ACS web console or use the CLI command 'show version' to retrieve the installed version numberAffected if Any version of Cisco Secure ACS is running, since all versions are affected according to the CVE
-
Verify RBAC is enabledCheck the ACS configuration for Role-Based Access Control settings - typically found under Users and Identity Stores or Administration settings in the ACS web interfaceAffected if RBAC feature is configured and active in the ACS deployment
-
Review user role assignmentsExamine user accounts and their assigned roles in the ACS administrative console, specifically looking for any accounts with Network Device Administrator privileges that may not have been intentionally grantedAffected if Users possess elevated privileges (Create, Delete, Read, Update operations) beyond their intended role assignments
-
Audit administrative action logsReview ACS logging and audit trails for administrative actions, particularly operations performed via HTTP that may indicate unauthorized privilege escalation attemptsAffected if Administrative actions show operations performed by users whose assigned roles should not permit such activities
If Cisco Secure ACS is deployed in your environment, you are affected by this vulnerability since all versions contain the RBAC privilege escalation flaw.
Generated from the published advisory. Verify against your own configuration.
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 the Cisco patch for bug ID CSCuq79034. Until then, limit administrative access to ACS to trusted IP addresses only and closely audit user privilege assignments and administrative actions for signs of unauthorized privilege escalation.
