Severity Level:
===============
High
Technical Details & Description:
================================
A local command injection vulnerability has been discovered in the official in
the official My Photo Wifi Share & Picture Server v1.1 iOS mobile
web-application.
The command injection bug allows remote attackers to inject local commands via
vulnerable system values to compromise the mobile service or application.
The local vulnerability is located in the vulnerable `albumname` value. Local
attackers are able to inject own malicious system specific commands or
path requests as the albumname value. The injection requires an active sync via
`Share My Photos` (wifi) module. The execution of the local command
inject via albumname value on sync occurs in the album dir index list. The
security risk of the local command/path inject vulnerability is estimated
as high(-) with a cvss (common vulnerability scoring system) count of 6.1(-).
Exploitation of the command/path inject vulnerability requires a low privileged
iOS device account with restricted access and no user interaction.
Successful exploitation of the vulnerability results in unauthorized execution
of system specific commands and unauthorized path value requests to
compromise the mobile iOS application or the connected device components.
Request Method(s):
[+] Sync [iPhone or iPad]
Vulnerable Input(s):
[+] Album (Name)
Vulnerable Parameter(s):
[+] albumname (path value)
Affected Module(s):
[+] Index - Album Dir Listing
Proof of Concept (PoC):
=======================
The local command inject web vulnerability can be exploited by local attackers
with low privileged device user account and without user interaction.
For security demonstration or to reproduce the web vulnerability follow the
provided information and steps below to continue.
Manually steps to reproduce the vulnerability ...
1. Download and install the My Photo Wifi Share & Picture Server v1.1 iOS
mobile web-application >
https://itunes.apple.com/de/app/my-photo-wifi-share-picture/id421260815
2. Start the default photo album app of iOS
3. Create a new album and select some pictures to include for sync
4. Now, the local attacker is able to inject a payload with as local system
specific command or path value request
5. After the albumname save the attacker starts the vulnerable My Photo Wifi
Share & Picture Server v1.1 iOS mobile web-application
6. Select the Album with the vulnerable injected command and use the share
album function
7. After the click on the share album button the remote attacker is able to
request the (localhost:8080) wifi interface (web-server)
8. The execution of the injected command via stable value on sync occurs in the
album dir index list
9. Successful reproduce of the local command injection web vulnerability!
PoC: Album(s) Dir Listing
<font size="16">Album: >"<>"./[LOCAL COMMAND INJECTION VULNERABILITY VIA
ALBUMNAME VALUE]<"></font></td></tr><tr></tr><tr>

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure parse of the vulnerable album name
value & input.
Filter and encode the output index album list to prevent local command
injection via phone sync.
Security Risk:
==============
The security risk of the local command inject web vulnerability is estimated as
high(-).
