Open and resolved caveats in TC6

Reference ID Summary

expected time to register to a SIP registrar server.

CSCub87346

When changing from IPv6 to IPv4, the endpoints continue to be SIP registered on

IPv6.

CSCub16191

TC endpoint unable to re-register to outbound proxy after VCS failure. Endpoint

registers for VCS1 as primary and VCS2 as secondary using outbound registration.

VCS1 goes to maintenance mode. When VCS1 comes back online, the endpoint is

still registered to VCS2.

Reference ID Summary

CSCud08102

SX20 USB port intermittently ends up in a bad state. Re-plug USB (or reboot the unit

if remotely) to get the USB-serial communication back up.

CSCud17924

If the remote control has low battery, it sends two messages when pushing the ‘ok’ /

‘V’ button. This can be observed by enabling self view and point the remote towards

the camera to see the IR pulses. If the camera is used for IR, the codec interprets the

first message correctly as ‘ok’, but the second message is interpreted as volume

down.

CSCud96071

If a password for a user/admin is set to an empty string, the web portal will allow that

user/admin to log in with arbitrary data in the password field. If an attacker can change

the password to an empty string, then a user entering their correct password into the

web portal would not detect the change. Password checks should be an exact match,

including empty passwords.

CSCub20957

DHCP option 150 is not requested unless CDP is enabled. CDP is enabled by setting

xConfiguration Network 1 VLAN Voice Mode: Auto.

CSCuc83851

There exist executables on the endpoints running TC software that are compiled

without built-in object size checking (BOSC) and stack smashing protections.
