InfraPower PPS-02-S Q213V1 Authentication Bypass

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
