Description (partial)


Cisco WAAS includes a version of OpenSSL (1.0.0a with patches) that some scanners may flag as affected by the vulnerabilities identified by the 
following Common Vulnerability and Exposures (CVE) IDs:

CVE-2013-6450 , CVE-2013-6449  and  CVE-2013-4353  

Cisco has analyzed these vulnerabilities and concluded that the product is not impacted.

Not applicable

WAAS is not vulnerable as it doesn'tt support the affected features - TLS 1.2, DTLS and Next Protocol Negotiation.

The code fix applied via this bug was the patch of CVE-2013-6450, given that OpenSSL 1.0.0a has code support for DTLS but the path to this code 
is not reached via any configuration of the WAAS.
