CVE-2023-3380 Scanner

The WAVLINK WN579X3 is a router commonly used in home and small office environments. It is designed to extend Wi-Fi coverage and improve network connectivity. Developed by WAVLINK, the product is utilized globally by both individuals and organizations to ensure robust wireless connectivity. Known for its user-friendly interface and ease of setup, the WAVLINK WN579X3 is a popular choice in the consumer market. It supports various networking protocols and provides essential features for managing and securing a home network. The WAVLINK brand is recognized for delivering reliable networking solutions across different audience segments.

The Remote Code Execution (RCE) vulnerability allows attackers to execute arbitrary code on the affected device without user authorization. This security flaw is critical because it can lead to full system compromise. Attackers can exploit this vulnerability to gain unauthorized access to network settings and compromise the security and integrity of the network. The vulnerability primarily targets the 'pingIp' parameter within the router's web interface. Due to a lack of input validation, malicious actors can leverage this vulnerability to inject and execute harmful scripts. Maintaining a secure configuration and ensuring systems are patched can mitigate exploitation risks.

The vulnerability in WAVLINK WN579X3 occurs due to improper handling of user input in the 'pingIp' parameter in the '/cgi-bin/adm.cgi' script. An attacker can craft a malicious HTTP request to exploit the vulnerability by injecting commands in the 'pingIp' parameter, bypassing normal security measures. The lack of validation allows the injection of OS commands, which the server executes, leading to remote command execution. This issue makes the router susceptible to systemic attacks that could affect overall network security. Monitoring network traffic and implementing input validation can considerably help in avoiding such vulnerabilities.

Exploiting this vulnerability could lead to unauthorized control over network hardware, making it possible to intercept data and control network traffic. Attackers could deploy malware, modify router settings, or control the flow of network traffic, thereby risking data breach and severe network disruptions. The effects of exploitation could extend beyond network compromise, potentially impacting connected devices as well. Malicious actors could use the compromised device as a launchpad to conduct further attacks against other systems. As a result, the significance of applying security patches and updates becomes paramount to prevent such security incidents.
