Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content. In order to serve static content, the application performs a check for the existence of specific characters in the URL (.css, .png etc). If it exists, it performs a fake login to give the request an active session to load the file and not redirect to the login page.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
