CVE-2020-29669

Name of the Vulnerable Software and Affected Versions Macally WIFISD2-2A82 Media and Travel Router version 2.000.010

Description The Guest user in the Macally WIFISD2-2A82 Media and Travel Router can reset its own password, which has a vulnerability that can be exploited to take over the administrator account, resulting in shell access.

Additionally, limit access to the /etc/shadow file to prevent the dumping of password hashes. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
