How the Exploit Works
In a nutshell, the command injection vulnerability works by exploiting the /cgi-bin/adm.cgi component of the Wavlink WL-WN579A3 v1.0. Specifically, this component does not properly sanitize user-supplied inputs, making it possible for an attacker to insert malicious commands. Once the malicious command is executed, the attacker can gain unauthorized access to the system or even execute further commands.
Conceptual Example Code
A conceptual example of how this vulnerability might be exploited might involve an HTTP request like the following:
POST /cgi-bin/adm.cgi HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
cmd=;ls -la; # List all files in the current directoryIn this example, the attacker is injecting a command (`;ls -la;`) to list all files in the current directory. Note that this is a conceptual example and the actual exploit may involve different commands or methods.
Mitigation Guidance
To protect against this vulnerability, users are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation measure. These systems can be configured to detect and block attempts to exploit this vulnerability.
