Exploit :  
The Program Was Enabled To process the Exception .  
The Exception is an access Violation to EAX by Flooding the CX in the ECX Register.  
  
[Imp Registers] :  
  
EAX 00190000 ASCII "Actx"  
ECX 00000041

MOVZX ECX,WORD PTR DS:[EDX+EAX]  
TEST CX,CX  
JE SHORT COMCTL32.720AB00B

---------------------------------------------------------------------------------------------------------  
Risks : HIGH  
  
The program is crashed when Executing it . ( Double click , the interface is shown up, charging boutton is up then Boom Crash ) .   
  
This exploit in the HUAWEI Modem is concidered a high one beacause the Attacker can edit the XML and lang files reffering to direct DLLs .  
Which can cause in most of the times an edit of sensitive Lines. So , the attacker can have the privileges to bypass the program Authetification or to use the exception handling to DoS the users program until it's reinstalled (Not Restarded) . A normal user can't know the source of the crash problem which is related to the XML files . Nobody search or read in these files most of the times .  
Then he will stay without Internet connection for a no short period of time , until reinstalling the program or contacting the vendor .  
  
----------------------------------------------------------------------------------------------------------  
How To Exploit : (USE IT AT YOUR OWN RISK , Je ne suis pas responsable de ce qui est fait par cette vulnerabilité) I'm not responsible of any harm .  
  
Go to ----> C:\Progam Files\Internet Mobile\plugins\SMSUIPlugin (FOR Example)  
Now open the lang files ---> French And English . SMSUIPlugin_fr-fr and SMSUIPlugin_en-us   
Replace the line :   
<item name="IDS_PLUGIN_NAME">Texte</item> and   
  
<item name="IDS_PLUGIN_MENUITEM">Message &Texte</item> and this one   
  
<item name="IDS_TREE_DINBOX">Boite de réception</item> Same Names just in english instead french  
  
-------------------------------------------  
  
Replace them with that (for example) :  
  
This : <item name="IDS_PLUGIN_NAME">Texte</item>  
  
Will become This : <item name="IDS_PLUGIN_NAME"> Very Very Very Huge Number Of AAA or whatever </item>  
  
and the same thing for the other lines shown before . This will make the program Crash when it's opened .  
  
The victim will be not able to run the software again until it's reinstalled .  
  
A script will be soon available to replace automatically the Lang files . ( PoC )
