Dasan GPON Router Authentication Bypass via ?images Parameter
CVE-2018-10561 is an authentication bypass vulnerability in DASAN Zhone Solutions GPON home routers. The issue allows an unauthenticated remote attacker to bypass the device’s web authentication checks by appending the string "?images" to URLs that normally require authentication, such as /menu.html?images/ or /GponForm/diag_FORM?images/. As described in the provided content, this flaw permits access to authenticated management functionality without valid credentials, effectively exposing administrative device operations to remote users.
