There is an input validation vulnerability in a PON terminal product of ZTE, which supports the creation of WAN connections through WEB management pages. The front-end limits the length of the WAN connection name that is created, but the HTTP proxy is available to be used to bypass the limitation. An attacker can exploit the vulnerability to tamper with the parameter value. This affects: ZTE F680 V9.0.10P1N6

ZTE's PON terminal product is impacted by the access control vulnerability. Due to the system not performing correct access control on some program interfaces, an attacker could use this vulnerability to tamper with the program interface parameters to perform unauthenticated operations. This affects: <ZTE F680><V9.0.10P1N6>
