CVE intelligence and bounded remediation
CVE-2020-29669 — In the Macally WIFISD2-2A82 Media and Travel Router 2.000.010, the Guest user is able to reset its own password
In the Macally WIFISD2-2A82 Media and Travel Router 2.000.010, the Guest user is able to reset its own password. This process has a vulnerability which can be used to take over the administrator account and results in shell access. As the admin user may read the /etc/shadow file, the password hashes of each user (including root) can be dumped. The root hash can be cracked easily which results in a complete system compromise.

Matched remediation archetype
Authentication bypass and missing authentication
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
- Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
- Review session, token, credential, and proxy trust configuration without attempting account takeover.
Remediate safely
- Apply the supported fix and centralize fail-closed authentication before protected request handling.
- Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
- Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
