CVE-2015-8703
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedZTE ZXHN H108N R1A devices before ZTE.bhs.ZXHNH108NR1A.k_PE and ZXV10 W300 devices W300V1.0.0f_ER1_PE allow remote authenticated users to bypass intended access restrictions, and discover credentials and keys, by reading the configuration file, a different vulnerability than CVE-2015-7248.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAuthenticated users on affected ZTE ZXHN H108N and ZXV10 W300 routers can read the device configuration file, which exposes stored credentials and encryption keys that should be protected. This bypasses intended access controls by allowing any authenticated user to obtain sensitive authentication material.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify router modelLog into the router web interface or check the device label to confirm the model is either ZTE ZXHN H108N or ZTE ZXV10 W300Affected if Router model is ZXHN H108N or ZXV10 W300
-
Check firmware version on H108NNavigate to the router web admin interface, look in Status or Management section for firmware version. Compare against the affected range: versions <= zte.bhs.zxhnh108nr1a.h_peAffected if Firmware version is zte.bhs.zxhnh108nr1a.h_pe or earlier
-
Check firmware version on W300Navigate to the router web admin interface, look in Status or Management section for firmware version. Compare against the affected range: versions <= w300v1.0.0f_er1_peAffected if Firmware version is w300v1.0.0f_er1_pe or earlier
-
Verify authenticated access existsConfirm you have valid login credentials for the router administrative interfaceAffected if You can log into the router as any user (admin or limited user)
-
Test config file accessAs an authenticated user, attempt to access the device configuration file or backup settings page. Common endpoints include /backupsettings.conf, /dumpcfg, or a settings export feature. If the file downloads or displays and contains plaintext usernames and passwords, the vulnerability is present.Affected if Configuration file is downloadable by any authenticated user and contains plaintext credentials or encryption keys
If the router is a ZXHN H108N or ZXV10 W300 with firmware at or below the specified version limits AND any authenticated user can retrieve the config file containing exposed credentials, the environment is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate router firmware to the patched version (ZTE.bhs.ZXHNH108NR1A.k_PE or later for H108N, and W300V1.0.0f_ER1_PE or later for W300). If updates are unavailable, restrict administrative interface access to trusted networks only.
