Technical Details & Description:  
================================  
An insecure session validation web vulnerability has been discovered in  
the official SMACom v1.2.0 mobile ios web-application.  
The vulnerability becomes visible through insecure transmitted session  
credentials like passwords or keys.  
  
The vulnerability is located in the session handling of the `password`  
authentication parameter of the wifi photo transfer module.  
Users can setup there pin for authentication to access the wifi user  
interface. The web-server is not secured by ssl and transmits  
the `password` for the wifi authentication in plain-text. Remote  
attackers with network access privileges or on public wifis access  
are able to read the authentication credentials and followup requests  
with the password via man in the middle attack. The password  
is transmitted as plain-text and is used in the visible session  
parameter requested on each GET index attempt.  
  
Next to that we want to mention as well that the authentication is not  
protected against any bruteforce attempts which allowed us  
to quickly crack any 4-6 digits pins from the default generator within  
minutes.  
  
Successful exploitation of the vulnerability results in mobile wifi  
application file-system compromise and information leaks.  
  
Request Method(s):  
[+] GET  
  
Vulnerable Function(s):  
[+] Auth  
  
Vulnerable Module(s):  
[+] password  
  
  
Proof of Concept (PoC):  
=======================  
The vulnerability can be exploited by remote attackers with network  
access without privileged application user account.
