The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
None
A
There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

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.

Security Risk:
==============
The security risk of the insecure session validation web vulnerability
in the mobile ios web application is estimated as high.
