Create netgear-router-auth-bypass.yaml NETGEAR decided to use to check if a page has “.jpg”, “.gif” or “ess_” substrings, trying to match the entire URL. We can therefore access any page on the device, including those that require authentication, by appending a GET variable with the relevant substring (like “?.gif”).

description: NETGEAR DGN2200v1 Router does not require authentication if a page has ".jpg", ".gif", or "ess_" substrings, however matches the entire URL. Any page on the device can therefore be accessed, including those that require authentication, by appending a GET variable with the relevant substring (e.g., "?.gif").
Removed pipe (|) character from references, because the structure requires it to be a string slice, not a string Related nuclei tickets: * #259 - dynamic key-value field support for template information * #940 - new infos in template * #834 * RES-84
