    Technical Details & Description:
    ================================
    An arbitrary code execution vulnerability has been discovered in the official Linkus Photo Manager Pro v4.4.0 iOS mobile web-application.
    The vulnerability allows remote attackers to execute malicious codes on the application-side of the vulnerable app to compromise the 
    target mobile device.
    
    The vulnerability is located in the `folderName` value of the `newfolder.action` module. Remote attackers are able to manipulate the 
    `folderName` value in the `index.html#?w=300` file POST method request to compromise the application, user session information or connected 
    device components. The attacker tampers the new Folder POST method request to exchange the regular folderName value with special crafted code. 
    The input context is becomes visible at the main index service or subfolder (path). The vector of the vulnerability is located on the application-side. 
    
    The security risk of the arbitrary code execution vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.6.
    Exploitation of the arbitrary code execution vulnerability requires no user interaction or privileged web-application user account with password.
    Successful exploitation of the vulnerability results in session hijacking, persistent phishing, persistent external redirects and persistent 
    manipulation function or connected module context.
    
    Request Method(s):

    Proof of Concept (PoC):
    =======================
    The code execution vulnerability can be exploited by remote attackers without privileged application user account or user interaction.

    Solution - Fix & Patch:
    =======================
    The vulnerability can be patched by a secure parse and encode of the vulnerable folderName value. Restrict the input and filter the context by usage of a own exception to 
    prevent the application-side code execution.
    
    
    Security Risk:
    ==============
    The security risk of the code execution vulnerability in the photo manager wifi service is estimated as high. (CVSS 8.6)
