CVE-2022-48164 Scanner

The Wavlink WL-WN533A8 is a wireless networking device used for expanding Wi-Fi coverage in both home and office environments. It connects to various Wi-Fi networks and allows users to improve internet connectivity across larger areas. The device operates on firmware that can be accessed by administrators to configure network settings. Due to its use in home and office networking, its firmware needs to be securely configured to prevent unauthorized access. This vulnerability is a security risk that can expose sensitive user data.

The CVE-2022-48164 vulnerability in Wavlink WL-WN533A8 allows unauthenticated attackers to exploit an access control issue in the firmware. The vulnerability is present in the /cgi-bin/ExportLogs.sh component, where attackers can download sensitive configuration data and log files without authentication. This data can contain admin credentials and other sensitive information. Attackers exploiting this vulnerability can gain unauthorized access to sensitive user details, leading to potential information exposure.

This vulnerability is triggered when an attacker sends an HTTP GET request to the /cgi-bin/ExportLogs.sh endpoint of the device. The request returns sensitive data in the form of configuration and log files, which contain critical details such as admin credentials. The vulnerability exists because the device does not enforce proper authentication for this endpoint. The attacker can exploit this issue by simply accessing the URL, without needing any authentication credentials. Successful exploitation can lead to significant information leakage, allowing attackers to gain unauthorized access to critical data.

If exploited, this vulnerability can lead to the exposure of sensitive configuration data, including admin credentials. This can allow attackers to access the device's administrative functions, potentially compromising the device or network. Malicious users may also gain insight into Wi-Fi credentials or other sensitive configurations. The lack of authentication controls for this endpoint makes it easier for attackers to exploit. This poses a significant security risk to users of the Wavlink WL-WN533A8.
