Hi!

Our AP9617 card behaves a bit differently, but still, the password checks out... It's too in a Silicon 10 kVA UPS, but the card can be used in everything from the smallest BackUPS to huge Silicons.

*** Background:
APC (American Power Conversion) SmartSwitch and UPS (uninterruptible power
supply) products have a Web and SNMP management card installed that permits
local serial console, TELNET, web and SNMP management, monitoring and
mains power control of attached devices.


*** The Problem:
APC SmartSlot Web/SNMP management cards have a "backdoor" password that can
be abused to extract plain text username/password details for all accounts
and hence gain unauthorised full control of the device.
