Can you explain this vulnerability to me?

CVE-2025-49599 is a Broken Function Level Authorization vulnerability in Huawei ONT devices (models EG8141A5, EG8145V5, and EG8145V5-V2). It allows the Epuser account to disable the ONT firewall functionality, such as removing the default blocking of SSH and TELNET TCP ports, thereby bypassing function-level access controls within the firewall feature. [1]


How can this vulnerability impact me? :

This vulnerability can allow an attacker with access to the Epuser account to disable firewall protections on the affected ONT devices. This could lead to unauthorized access or manipulation of the device by exposing services like SSH and TELNET that are normally blocked, increasing the risk of further compromise or network intrusion.
