The H3-2s home gateway discussed here is identified as HWVer-A320 running V32.AA1.01. On this device, there are separate privilege levels for the regular user account and the higher-level administrator account, and the administrator interface exposes additional sections such as Application and Diagnostics.
Rather than reproducing instructions for extracting or changing privileged credentials, it is more useful to understand the security issue itself: on some gateways of this type, local management data includes account records for both the ordinary user and the higher-permission administrator account. In the configuration data, those records appear under DevAuthInfo, where User represents the account name and Pass represents the password. The same data structure also includes the lower-level user account.
That means anyone with unauthorized access to the management environment could potentially read or alter credential information, which is a serious security concern for a device that controls home networking, internet access, and diagnostics.
Device details noted for this model:
- Model: H3-2s
- Hardware version: HWVer-A320
- Software version: V32.AA1.01
The original walkthrough relied on Windows' built-in Telnet client and the router's local management interface. If you legitimately own this device and need higher-level access, the safer options are:
- use the default reset procedure documented by the operator or manufacturer;
- sign in with the credentials supplied for your service account;
- contact your ISP or device provider to request authorized administrator access or support;
- update firmware if a newer release closes hidden management exposure;
- change any passwords you are officially allowed to manage and disable unnecessary local management features.
If your concern is security auditing rather than password recovery, the important takeaway is that a gateway storing multiple privilege tiers in readable local configuration data is a risk. Any exposed debug interface, hidden local endpoint, or legacy service such as Telnet increases the attack surface and should be reviewed carefully.
