pnpm 10.12 Introduces Global Virtual Store and Expanded Version Catalogs
pnpm 10.12.1 introduces a global virtual store for faster installs and new options for managing dependencies with version catalogs.
A library written for finding insertion points in HTTP requests and injecting payloads.
HTTPInsert is a library written for finding insertion points in HTTP requests and injecting palyoads.
There are countless scanners parsing for insertion points in their own unique way, some better than others. This is my attempt at making a simple to use library for finding and handling insertion points, making it easier to create new and awesome vulnerabilitiy scanners.
python3 -m pip install httpinsert
from httpinsert import Location, requests_request
from httpinsert.insertion_points import InsertionPoint, find_insertion_points
from requests import Request
requests_req = Request("GET","https://example.com/endpoint?param=value&other=param")
httpinsert_request = requests_request(requests_req)
insertion_points = find_insertion_points(httpinsert_request,default=True,location="Query") # Specifying default=True excludes multiple params such as keys
payload = "SomePayloadToInject"
for insertion_point in insertion_points:
insertion = insertion_point.insert(payload,httpinsert_request,format_payload=True)
resp, response_time, error = httpinsert_request.send(insertions=[insertion])
print(resp,response_time,error,insertion.full_section) # full_section is the full section after the payload is injected. In this case full_section is the full URL.
print(insertion.full_section == resp.request.url) # True
It is possible to create custom logic for finding insertion points and injecting payloads.
Here's an example of how to create a new insertion point between all dashes:
class Dashes(Location):
def find_insertion_points(self,request):
parsed_url = urlparse(request.url)
path = parsed_url.path
segments = path.split("-")
insertion_points = []
for c,segment in enumerate(segments):
insertion_points.append(InsertionPoint(self,"dashes", str(c), segment))
return insertion_points
def insert_payload(self,request,insertion_point,payload,default_encoding):
if default_encoding is True:
if isinstance(payload,str):
payload=quote(payload) # Encode the payload
else:
payload = [quote(i) for i in payload]
parsed_url = urlparse(request.url)
path = parsed_url.path
segments = path.split("-")
if int(insertion_point.key) == len(segments):
path+=payload
else:
segments[int(insertion_point.key)] = payload
path = "-".join(segments)
url = urlunparse(parsed_url._replace(path=path))
request.url=url
return request,request.url
Dashes() # Important to create the object to include this object in the list of custom insertion points
