[python] The tuple (*) argument of a call cannot step to function parameter for the CommandInjectionCustomizations flow #19900
Description
In Python, when passing the typle (*) argument to function parameters, the taint propagation chain breaks. As shown in the following code snippet, this issue occurs. Are there plans to support this scenario? How do i resolve this issue?
from django.contrib.auth.decorators import login_required
from django.conf.urls import url
import os
def build_cmd(cmd: str):
cmd = cmd + "; touch aa"
print(cmd)
return cmd
@login_required
def GetOperateLog(request):
cmd = request.POST.get('cmd', None)
args = []
args.append(cmd)
cmd3 = build_cmd(*args)
os.system(cmd3)
urlpatterns = [
url(r'^GetOperateLog', GetOperateLog, name='GetOperateLog'),
]This is the taint propagation flow.
