Cisco Bug: CSCsz26548 - TCP segment trim to right edge causing ssl alerts
Apr 23, 2010
- Cisco ACE 4700 Series Application Control Engine Appliances
Known Affected Releases
Symptom: The customer is using a home-grown application that rides on HTTPS and terminates on the ACE module, then is sent in clear-text to a backend server. When transferring large file the ACE sends an encrypted alert to the client. Just prior to this, it reduces its TCP window to zero, then bumps it up, and after it gets the packet that it was ACK'ing for from the client, it sends the encrypted alert. Conditions: The network is losey with duplicate packets, retransmission and long delays.
