An issue was discovered on Wavlink Jetstream devices where a crafted POST request can be sent to adm.cgi that will result in the execution of the supplied command if there is an active session at the same time. The POST request itself is not validated to ensure it came from the active session. Affected devices are: Wavlink WN530HG4, Wavlink WN575A3, Wavlink WN579G3,Wavlink WN531G3, Wavlink WN533A8, Wavlink WN531A6, Wavlink WN551K1, Wavlink WN535G3, Wavlink WN530H4, Wavlink WN57X93, WN572HG3, Wavlink WN578A2, Wavlink WN579G3, Wavlink WN579X3, and Jetstream AC3000/ERAC3000

A vulnerability was found in WAVLINK WN530H4, WN530HG4 and WN572HG3 up to 20221028. It has been classified as critical.

An issue was discovered where there are multiple externally accessible pages that do not require any sort of authentication, and store system information for internal usage. The devices automatically query these pages to update dashboards and other statistics, but the pages can be accessed externally without any authentication. All the pages follow the naming convention live(string).shtml. Among the information disclosed is: interface status logs, IP address of the device, MAC address of the device, model and current firmware version, location, all running processes, all interfaces and their statuses, all current DHCP leases and the associated hostnames, all other wireless networks in range of the router, memory statistics, and components of the configuration of the device such as enabled features.

An issue was discovered in Wavlink WN530HG4, Wavlink WN531G3, Wavlink WN533A8, and Wavlink WN551K1 affecting /cgi-bin/ExportAllSettings.sh where a crafted POST request returns the current configuration of the device, including the administrator password. No authentication is required. The attacker must perform a decryption step, but all decryption information is readily available.

An issue was discovered where a page is exposed that has the current administrator password in cleartext in the source code of the page. No authentication is required in order to reach the page (a certain live?.shtml page with the variable syspasswd). Affected Devices: Wavlink WN530HG4, Wavlink WN531G3, and Wavlink WN572HG3

An access control issue in Wavlink WN530HG4 M30HG4.V5030.191116 allows attackers to obtain usernames and passwords via view-source:http://IPADDRESS/setsafety.shtml?r=52300 and searching for [var syspasswd].
