|
||
Version: 0.12.7.2
|
||
CVE: CVE-2018-7289
|
||
|
||
|
||
Details:
|
||
--------
|
||
An issue was discovered in armadito-windows-driver/src/communication.c affecting Armadito 0.12.7.2 and previous versions.
|
||
Malware with filenames containing pure UTF-16 characters can bypass detection.
|
||
The user-mode service will fail to open the file for scanning after the conversion is done from Unicode to ANSI.
|
||
This happens because characters that cannot be converted from Unicode are replaced with the '?' character.
|
||
|
||
The code responsible for this issue is located in armadito-windows-driver/src/communication.c
|
||
|
||
========================================================================================================
|
||
// Convert unicode string to ansi string for ring 3 process.
|
||
ntStatus = RtlUnicodeStringToAnsiString(&AnsiString, (PCUNICODE_STRING)FilePath, TRUE);
|
||
if(!NT_SUCCESS(ntStatus)){
|
||
DbgPrint("[-] Error :: ArmaditoGuard!SendScanOrder :: RtlUnicodeStringToAnsiString() routine failed !! \n");
|
||
__leave;
|
||
}
|
||
========================================================================================================
|
||
|
||
The two examples below demonstrate the bug.
|
||
In the first case, the filename is in Arabic and in the second, the filename's first letter is the greek M (U+039C).
|
||
|
||
|
||
Original filename:
|
||
مرحبا.exe : 0645 0631 062d 0628 0627 002e 0065 0078 0065
|
||
|
||
Converted to ANSI by Armadito:
|
||
?????.exe : 3f 3f 3f 3f 3f 2e 65 78 65
|
||
|
||
=============================
|
||
|
||
Original filename:
|
||
Μalware.exe : 039c 0061 006c 0077 0061 0072 0065 002e 0065 0078 0065
|
||
|
||
Converted to ANSI by Armadito:
|
||
?alware.exe : 3f 61 6c 77 61 72 65 2e 65 78 65
