Private Photos v1.0 iOS - Persistent Path Web Vulnerability
Common Vulnerability Scoring System:
You must have some private photos you don`t want others peeping. Private photos is the perfect app to keep
your private photos safely in your iPad. Photos are protected by a password and you won`t worry your privacy
when friends playing your iPad.
Now you can enjoy your private photos anytime, anywhere with your iPad. The built-in viewer can zoom in,
zoom out, and slideshow photos, just like the experience with the native photos app.
- One password protection for photos viewing and transferring
- Web access via WIFI
- Multiple photos transferring
- Multi-touch support: swipe, zoom
- Slide show
Transferring your photos to the app is simple. You can easily access your private photos via WIFI from
desktop/laptop`s web browser (Make sure your desktop/laptop is in the same WIFI network as your iPad).
When connected to your iPad from web browser, you can select and transfer multiple photos with one click.
The transferring is also protected by the same password.

The Vulnerability Laboratory Research Team discovered 2 persistent web vulnerabilities in the Private Photos v1.0
application (Apple iOS - iPad & iPhone).
2013-07-25: Public Disclosure (Vulnerability Laboratory)
Product: Private Photos 1.0
A persistent input validation web vulnerability is detected in the Private Photos v1.0 application (Apple iOS - iPad &
The bug allows an attacker (remote) to implement/inject malicious own malicious persistent script codes (application
The vulnerability is located in the `Add Directory` module of the web-server (http://localhost:8080) when processing to
request via POST method manipulated `folder-names`. The folder name will be changed to the path value without secure
encode or parse. The injected script code will be executed in the path listing were the attacker injected earlier the
and of course also in the index listing of the mobile web application.
There is a security protection to filter single and double quotes. When processing to inject the code a messagebox pops
with the illegal characters exception. To bypass the exception the remote attacker can use simple obfuscated strings,
or html/js script codes (frames, scripts, img, embed and co.) without single & double quotes.
Exploitation of the persistent web vulnerability requires low user interaction and a local low privilege mobile
with a password. Successful exploitation of the vulnerability can lead to persistent session hijacking (customers),
via persistent web attacks, persistent phishing or persistent module context manipulation.

Proof of Concept:
The persistent input validation web vulnerability can be exploited by remote attackers with low privilege application
and low or medium required user interaction. For demonstration or reproduce ...

Note: The application will attach the injected payload to the main server as folder/path name. example:
The vulnerability can be patched by a restriction of the foldername input and a secure encoding of the input.
The output location of the foldername and path needs to be filtered and encoded by a secure mechanism.
The security risk of the persistent script code inject web vulnerability is estimated as medium.
