How the Exploit Works
The vulnerability arises from insufficient sanitization of user-supplied input in the /cgi-bin/cgi_vista.cgi executable. This executable is passed to a system-level function call. An attacker with valid credentials can craft malicious input, which when processed by the wifi extender, leads to arbitrary command execution with root privileges.
Conceptual Example Code
Let’s illustrate how the exploit might work conceptually. An attacker might send a specially crafted HTTP POST request similar to the one below:
POST /cgi-bin/cgi_vista.cgi HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
Authorization: Basic [Base64-encoded credentials]
cmd=; [arbitrary command]In this example, the `cmd` parameter is manipulated with an arbitrary command, which gets executed with root privileges due to the vulnerability.
Mitigation
The recommended course of action is to apply the vendor patch as soon as it is available. Until then, users can implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation step. These solutions can help by blocking or alerting on suspicious traffic towards the affected endpoint.
