Re: [Full-disclosure] another filename bypass vulnerability - fromcmd.exe

["Morning Wood" <se_cur_ity@xxxxxxxxxxx>]

I think the OP was getting at this being an AV bypass vector for worms and
other malware that can interact with cmd.exe .
Theroy being that AV will scan by extention ( malware.exe vs malware.ext )
and thus evade detection but yet be executeable.
In light, informal testing this appears to be a realistic scenario that
provides yet another vector for AV bypass. On test systems,
"c:\>malware.exe.txt" runs the malware.exe, and does not open notepad. (
cmd.exe parses the file header, explorer.exe uses .extention )
