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

The CVE-2025-4810 vulnerability is a critical security flaw discovered in Tenda AC7 15.03.06.44, a widely used WiFi router. The vulnerability has been categorized as a stack-based buffer overflow vulnerability, which can potentially compromise the entire system or lead to data leakage. The vulnerability affects a specific function of the router, making it susceptible to remote attacks<\/a>. This vulnerability is significant due to its potential<\/a> for widespread impact.<\/p>\n

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

CVE ID: CVE-2025-4810
\nSeverity: Critical, CVSS Score 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 AC7<\/a> | 15.03.06.44<\/p>\n

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

The vulnerability exists in the formSetRebootTimer function of the \/goform\/SetRebootTimer file in Tenda<\/a> AC7. The function is designed to accept a user-specified reboot_time argument. However, due to insufficient validation of this argument, an attacker can manipulate the reboot_time argument to trigger a buffer overflow<\/a>. This overflow can lead to arbitrary code execution<\/a> thus giving the attacker control over the system.<\/p>\n

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

This conceptual example represents how an attacker might exploit<\/a> this vulnerability. In this case, a malicious HTTP POST request<\/a> is made to the endpoint that accepts the reboot_time argument.<\/p>\n

POST \/goform\/SetRebootTimer HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"reboot_time\": \"VERY LONG STRING THAT TRIGGERS BUFFER OVERFLOW...\" }<\/code><\/pre>\n
The “reboot_time” argument is filled with an excessively long string that triggers a buffer overflow<\/a>, leading to potential system compromises and data leakage if successfully exploited.<\/p>\n
Mitigation and Patch Information<\/strong><\/p>\n
Users are advised to apply the vendor patch as soon as possible to mitigate this vulnerability<\/a>. In case the patch is not immediately available or cannot be applied immediately, users can use a Web<\/a> Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can detect and block attempts to exploit this vulnerability<\/a>, providing a layer of protection until the patch can be applied.<\/p>\n","protected":false},"excerpt":{"rendered":"
