Overview<\/strong><\/p>\n

A newly discovered vulnerability, CVE-2025-4298, poses a significant risk to users of Tenda AC1206 up to version 15.03.06.23. This vulnerability, classified as critical due to its potential for system compromise and data leakage, affects the file \/goform\/setcfm specifically its function formSetCfm. The manipulation of this function can cause a buffer overflow<\/a> that can be exploited remotely. The discovery of this vulnerability, whose exploit has already been disclosed to the public, underscores the critical need for cybersecurity<\/a> vigilance and robust, consistent patch management.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-4298
\nSeverity: Critical (CVSS: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Tenda AC1206 | Up to 15.03.06.23<\/p>\n

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

The vulnerability stems from improper input validation<\/a> in the formSetCfm function of the \/goform\/setcfm file. An attacker can craft a specially designed request to manipulate the system’s buffer<\/a>, causing an overflow. This overflow can lead to unexpected behaviors, such as the execution of arbitrary code<\/a> or the crash of the system. This vulnerability can be exploited remotely<\/a> without any form of authentication or user interaction, making it a prime target for malicious actors.<\/p>\n

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

Below is a conceptual example of how an attacker might exploit this vulnerability<\/a>. Note that this is a simplified example and actual exploitation may require more complex steps.<\/p>\n

POST \/goform\/setcfm HTTP\/1.1\nHost: vulnerable-router.example.com\nContent-Type: application\/json\n{ \"buffer_overflow_trigger_payload\": \"...\" }<\/code><\/pre>\n
In this example, the “buffer_overflow_trigger_payload” would be specifically designed to exploit the vulnerability and cause a buffer overflow<\/a>.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The best mitigation strategy for this vulnerability<\/a> is to apply the vendor-provided patch as soon as possible. If applying the patch is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure can help protect against potential<\/a> attacks. However, these measures should not replace patching as they may not provide complete protection against all possible exploitation methods.<\/p>\n","protected":false},"excerpt":{"rendered":"
