Exploit

Authenticated bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows unauthenticated user to get access to content.

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.
