TPAM appliances (2.5.904 - 2.5.917)
The 3DES cipher exists. A hotfix has been made available here
that will disable support of the 3DES ciphers for TLS connections on the TPAM console appliances.
DPA and CacheServers
The 3DES cipher exists. The SWEET32 vulnerability indicates that it can only be exploited during very long-lived HTTPS sessions that send a large number of requests in the same TLS connection. Requests made to a DPA or Cache appliances do not meet this criterion for the vulnerability to be exploited. Therefore, a hotfix is not required and the vulnerability scanner is reporting a false positive.
