Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from netcommwireless. Update nf20_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
