WAVLINK Quantum D4G (WL-WN531G3) running firmware versions M31G3.V5030.201204 and M31G3.V5030.200325 has an access control issue which allows unauthenticated attackers to download configuration data and log files.

The WAVLINK Quantum D4G (WN531G3) running firmware version M31G3.V5030.200325 does not utilize anti-CSRF tokens, which, when combined with other issues (such as CVE-2022-35518), can lead to remote, unauthenticated command execution.

The WAVLINK Quantum D4G (WN531G3) running firmware version M31G3.V5030.200325 uses IP addresses to hold sessions and does not not use session tokens. Therefore, if an attacker changes their IP address to match the logged-in administrator's, or is behind the same NAT as the logged in administrator, session takeover is possible.

Because the WAVLINK Quantum D4G (WN531G3) running firmware version M31G3.V5030.200325 and earlier communicates over HTTP and not HTTPS, and because the hashing mechanism does not rely on a server-supplied key, it is possible for an attacker with sufficient network access to capture the hashed password of a logged on user and use it in a classic Pass-the-Hash style attack.

A vulnerability is in the 'live_mfg.html' page of the WAVLINK AC1200, version WAVLINK-A42W-1.27.6-20180418, which can allow a remote attacker to access this page without any authentication. When processed, it exposes some key information of the manager of router.

A vulnerability is in the 'wx.html' page of the WAVLINK AC1200, version WAVLINK-A42W-1.27.6-20180418, which can allow a remote attacker to access this page without any authentication. When an unauthorized user accesses this page directly, it connects to this device as a friend of the device owner.

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 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. Affected devices: Affected devices are: Wavlink WN530HG4, Wavlink WN575A3, Wavlink WN579G3,Wavlink WN531G3, Wavlink WN533A8, Wavlink WN531A6, Wavlink WN551K1, Wavlink WN535G3, Wavlink WN53…
