Cisco Crowdsources Critical Announcements: SSL Certificate Changes on SPA-500 phones

The Cisco Small Business SPA-500 series phones (such as the SPA-502G, SPA-508G) include a Cisco-signed SSL certificate. Until very recently, all of the Cisco SPA-500-series phones shipped were signed by a Sipura certificate. Sipura was the Korean company that was bought by Linksys before Linksys was bought by Cisco.

Sometime after August 2013, Cisco Small Business started shipping phones signed with a different certificate. Cisco Small Business failed to inform the largest telephone company in the world so it could prepare for this change.

Cisco has issued a new certificate that can be used to verify the new client certificates. Dan Lukes used the Cisco discussion forum to helpfully post the new certificates. We’re all glad Cisco hosts the site to enable their customer Dan Lukes to post the information that Cisco should have posted.

Using Apache HTTPD, you can load the text below as a certificate, then setup a directory to require the client certificate:

        SSLCACertificateFile /etc/httpd/conf/ssl.crt/cisco_small_business_cert_20140802.crt
        <Location /spa500>
              SSLRequireSSL
              SSLVerifyClient require
              SSLVerifyDepth 10
        </Location>

In honor of the United States’ Belt-and-Suspenders approach to ebola prevention, 200OK.info is posting the certificate here.
