DescriptionCVE.org

Insufficiently Protected Credentials vulnerability in Zyxel Networks WAH7601 allows Retrieve Embedded Sensitive Data.

This issue affects WAH7601: through 20072026.

AnalysisAI

Insufficiently protected credentials in the Zyxel WAH7601 4G LTE mobile Wi-Fi router expose sensitive embedded data to unauthenticated remote attackers. All firmware versions through 20072026 are affected, and the CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation requiring no privileges or user interaction. No public exploit has been identified at time of analysis, and no CISA KEV listing is present, but the unauthenticated network-accessible nature of the flaw warrants prompt patching.

Technical ContextAI

CWE-522 (Insufficiently Protected Credentials) describes a class of flaw where credentials - such as admin passwords, Wi-Fi PSKs, ISP credentials, or API tokens - are stored or transmitted in a form that an attacker can retrieve without proper authorization controls. In embedded networking devices like the WAH7601, this most commonly manifests as credentials readable via an unprotected API endpoint, embedded in firmware images in cleartext, or exposed through the device management web interface without authentication. The WAH7601 is a Zyxel-branded 4G LTE mobile hotspot device providing shared internet access; its management interface and potential WAN-facing services constitute the network attack surface. The CPE data was not explicitly provided, but the affected product is identified as Zyxel WAH7601 running firmware versions up to and including 20072026 (a date-formatted firmware version string). The network attack vector (AV:N) in the provided CVSS vector is consistent with exploitation via a reachable management interface over LTE or local Wi-Fi, particularly if the device's admin panel is exposed to connected clients or the internet.

RemediationAI

Check the Zyxel security advisory portal for an updated firmware release for the WAH7601 that addresses this credential exposure. The provided reference (https://siberguvenlik.gov.tr/guvenlik-bildirimleri/detay/tr-26-0799) should be consulted for any interim guidance from USOM. No exact patched firmware version was identified in the available data, so administrators should monitor Zyxel's official support pages. As a compensating control, restrict access to the WAH7601 management interface to trusted clients only by disabling remote/WAN-side admin access if the firmware supports this option - note this does not eliminate the vulnerability if credentials are still retrievable by local Wi-Fi clients. Changing any default or embedded credentials immediately after identifying the affected device is advisable; be aware this may not fully mitigate the flaw if the underlying retrieval mechanism bypasses authentication. Network segmentation of devices using WAH7601 hotspots limits blast radius if credentials are exfiltrated.
