Nf20 Firmware

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.Show less

On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter. By providing a specific number of bytes, the instruction pointer is able to be overwritten on the stack and crashes the application at a known location.Show less
