Administrator credential disclosure via unauthenticated PNPX action
Published Dec 26, 2021 · Updated Aug 4, 2024
Authentication bypass in NETGEAR router firmware before the listed fixed releases allows remote attackers to read administrator credentials. The mini_http service exposes the PNPX_GetShareFolderList action through setup.cgi without authentication and returns the administrator password in plaintext. The attacker must reach the router's adjacent-network web interface; the disclosed credentials grant administrative portal access.
