Win afl crash immediately after start fuzzing : : : PROGRAM ABORT : CreateProcess failed, GLE=193

[Daniel0xcc]

Hey, I try to Fuzz some program with ( WIN-AFL ) and i got an issue that look like that :

**[-] PROGRAM ABORT : CreateProcess failed, GLE=193.
         Location : create_target_process(), c:\work\winafl\source\afl-fuzz.c:2330**

Most likely an error in your command line, e.g. does the path to the target .exe contain spaces (if so, you need to quote it).

I wrote it like this :
afl-fuzz.exe -Y -i x -o y -t 1000 — -fuzz_iterations 25000 — program.exe @@

-coverage_model ?
-target_model ?
-target_offset ?
Try adding these parameters

Ok I will try thanks, i have to put one of this Parma’s to instrumentation’s sector.

Note I use CMD it will not cause an issue ?

[MortalAndTry]

cmd is ok ,
I remember that the -nargs parameter is also required.
( if you use powershell you need a command like this ...... -- program.exe '@@' )

[Daniel0xcc]

I have a last question 😅.
Those params have a value ? for example ( -time 1000).

[Daniel0xcc]

can someone show me how he write that command ? please I stuck.. :(.

afl-fuzz.exe -i in -o out -D .......\DynamoRIO-Windows-7.1.17963-0\bin64 -t 20000 -- -coverage_module test.exe -fuzz_iterations 5000 -target_module test.exe -target_offset 0x13a0 -nargs 2 -- test.exe @@

You need to read the documentation and readme.txt carefully.
