Product | Affected Versions<\/p>\n

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

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

The vulnerability resides in the ‘setUssd’ function of the ‘\/cgi-bin\/cstecgi.cgi’ file. An attacker can manipulate the ‘ussd’ argument to inject operating system commands. This can be done remotely, without any user interaction or privileges. Successful exploitation allows unauthorized parties to take control of the system or access sensitive data.<\/p>\n

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

An example of how this vulnerability might be exploited is shown below. This conceptual HTTP request injects a malicious OS command via the ‘ussd’ parameter:<\/p>\n

POST \/cgi-bin\/cstecgi.cgi HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nsetUssd=;malicious_command<\/code><\/pre>\n
Mitigation and Vendor Response<\/strong><\/p>\n
At this time, the vendor has not responded to inquiries regarding this vulnerability. Users are highly recommended to apply the latest patches as soon as they are available. As a temporary mitigation method, users can implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block potential attacks exploiting this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
