The WebUI component allows an unauthenticated user to use a crafted HTTP API request to create, read, update, or delete entries in the subscriber database.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A request-validation issue was discovered in Open5GS 2.1.3 through 2.2.x before 2.2.1. The WebUI component allows an unauthenticated user to use a crafted HTTP API request to create, read, update, or delete entries in the subscriber database. For example, new administrative users can be added. The issue occurs because Express is not set up to require authentication.
