Product | Affected Versions<\/p>\n

Totolink LR1200GB<\/a> | 9.1.0u.6619_B20230130<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This vulnerability stems from a flaw in the setDiagnosisCfg function<\/a> of the \/cgi-bin\/cstecgi.cgi file. This flaw allows for an overflow in the stack-based buffer<\/a> when the ‘ip’ argument is manipulated, leading to the potential for an attacker to execute arbitrary code. The attack can be launched remotely<\/a>, adding to its severity and potential for widespread impact.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited<\/a>. This is a hypothetical HTTP request<\/a> that manipulates the ‘ip’ argument in a malicious way.<\/p>\n

POST \/cgi-bin\/cstecgi.cgi HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nsetDiagnosisCfg=1&ip=127.0.0.1;%20\/bin\/bash%20-c%20'cat%20\/etc\/passwd'<\/code><\/pre>\n
In this example, the attacker sends a POST request<\/a> that manipulates the ‘ip’ argument. The additional command after the IP address (`\/bin\/bash -c ‘cat \/etc\/passwd’`) is an example of a command that an attacker might use to exploit the buffer overflow and execute arbitrary code<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of the affected version of Totolink LR1204GB should immediately apply the patch provided<\/a> by the vendor. If the vendor patch is not available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Regularly update your systems<\/a> to ensure you are protected from this and other vulnerabilities.
\nNote: The vendor has been contacted about this disclosure but has not yet provided a response or a patch to address this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
