streamlit-geospatial: Server-Side Request Forgery

CVE-2024-41118 is a critical-severity server-side request forgery vulnerability in streamlit-geospatial from Opengeos, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version c4f81d9616d40c60584e36abb15300853a66e489 as the first without the flaw, so updating streamlit-geospatial to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.71% chance of exploitation within 30 days, higher than 54% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update streamlit-geospatial to c4f81d9616d40c60584e36abb15300853a66e489 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

streamlit-geospatial is a streamlit multipage app for geospatial applications. Prior to commit c4f81d9616d40c60584e36abb15300853a66e489, the `url` variable on line 47 of `pages/7_📦_Web_Map_Service.py` takes user input, which is passed to `get_layers` function, in which `url` is used with `get_wms_layer` method. `get_wms_layer` method creates a request to arbitrary destinations, leading to blind server-side request forgery. Commit c4f81d9616d40c60584e36abb15300853a66e489 fixes this issue.

The underlying weakness: Server-Side Request Forgery

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

How developers prevent this class of flaw

  • If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
  • If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
