3504 Security Exception

[domenic-nepote]

Hello, I am trying to get the fixed software for an AIR-CT3504-K9 WLC. I do not have support, but I found on the advisory where it says to call TAC and provide the URL. They are saying that they cannot help me out. Has anyone seen this or have recommendations? Multiple Cisco Products Switch Integrated Security Features DHCPv6 Denial of Service Vulnerability Thanks!

As per the link you provided above @domenic-nepote 

Customers Without Service Contracts

Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html

Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.

If first line TAC refuse to comply then ask them to escalate to their management because the statement is quite clear.
