InfraPower PPS-02-S Q213V1 suffers from an authentication bypass vulnerability. The device does not properly perform authentication, allowing it to be bypassed through cookie manipulation. The vulnerable function checkLogin() in 'Function.php' checks only if the 'Login' Cookie is empty or not, allowing easy bypass of the user security mechanisms.

InfraPower PPS-02-S Q213V1 Authentication Bypass Vulnerability
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: The device does not properly perform authentication, allowing
it to be bypassed through cookie manipulation. The vulnerable function
checkLogin() in 'Function.php' checks only if the 'Login' Cookie is empty
or not, allowing easy bypass of the user security mechanisms.
Tested on: Linux 2.6.28 (armv5tel)
lighttpd/1.4.30-devel-1321
PHP/5.3.9
SQLite/3.7.10
