This vulnerability is classified as an insecure direct object reference (IDOR) issue that allows attackers to gain elevated privileges and access certain administrative pages that should be restricted. This security flaw could potentially lead to unauthorized access to sensitive functions and information within the device.
Overview
The vulnerability exists in the web interface of Zyxel P1302-T10 v3 modems running firmware version 2.00(ABBX.3) or earlier.
