TACACS+ provides more control over the authorization of commands while in RADIUS, no external authorization of commands is supported. If you are already doing authentication on your network with NT or Server 2003, you can copy that user database to ACS and not have to create to lists of users. It is the box that will handle authentication of your wireless devices on your network. What is ACS in WIFI?ĪCS is a Radius Server.

It’s the job of Cisco Secure Access Control Server (ACS) to offer authentication, accounting, and authorization services to network devices. wireless – authenticates and authorizes wireless users and hosts and enforces wireless policies. How does Cisco ACS work? Cisco Access Control Server (ACS) is an authentication, authorization, and accounting (AAA) platform that lets you centrally manage access to network resources for a variety of access types, devices, and user groups. Cisco officials said they’re not aware of any public exploitation of the vulnerability yet.What Is Cisco Secure Acs? Cisco Secure Access Control Server (ACS) is a highly scalable, high-performance access control server that operates as a centralized RADIUS or TACACS+ server system and controls the authentication, authorization, and accounting (AAA) of users who access corporate resources through a network.
CISCO SECURE ACS VERSIONS PATCH
The vulnerability affects versions 4.0 through 4.2.1.15 of the Cisco ACS server and the patch is implemented in version 4.2.1.15.11. “Commands are executed in the context of the System user for Cisco Secure ACS authentication service running on Microsoft Windows. Cisco Secure ACS uses the standard RADIUS UDP port 1812 or 1645 for EAP-FAST authentication.”
CISCO SECURE ACS VERSIONS FULL
An exploit could allow the attacker to execute arbitrary commands on the Cisco Secure ACS server and take full control of the affected server,” the Cisco advisory says. An attacker could exploit this vulnerability by sending crafted EAP-FAST packets to an affected device. “The vulnerability is due to improper parsing of user identities used for EAP-FAST authentication. The company has issued a patch for the vulnerability, but there are no workarounds that can be implemented before the patch is rolled out.

Cisco officials said the flaw only exists when the ACS server is configured as a RADIUS server. The vulnerability is a highly critical one, as an attacker needs no authentication whatsoever and can take over control of the machine running the server. The bug results from a bad implementation of the EAP-FAST protocol and it affects a number of versions of the Cisco ACS. There is a critical remotely exploitable vulnerability in Cisco’s Secure Access Control Server which allows a remote attacker to take complete control of a vulnerable server.
