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

A critical vulnerability, identified as CVE-2025-7465, has been discovered in Tenda FH1201 version 1.2.0.14, a widely used networking device. This vulnerability can be exploited remotely, creating the potential for system compromise or data leakage. The flaw resides in the HTTP POST request handler, specifically in the fromRouteStatic function of the file \/goform\/fromRouteStatic. It is essential to address this vulnerability promptly due to its severity<\/a> and the wide usage of the affected product.<\/p>\n

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

CVE ID: CVE-2025-7465
\nSeverity: Critical, CVSS Score 8.8
\nAttack Vector: Remote
\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 FH1201<\/a> | 1.2.0.14<\/p>\n

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

The vulnerability arises from improper handling of HTTP POST requests<\/a> by the fromRouteStatic function in the \/goform\/fromRouteStatic file. An attacker can exploit<\/a> this flaw by sending a specially crafted HTTP POST request that contains an overly long ‘page’ argument. This could lead to a buffer overflow<\/a>, potentially allowing the attacker to execute arbitrary code or cause a denial of service.<\/p>\n

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

Here’s a hypothetical example of how an attacker might exploit the vulnerability:<\/p>\n

POST \/goform\/fromRouteStatic HTTP\/1.1\nHost: vulnerable-device\nContent-Type: application\/x-www-form-urlencoded\npage=A*50000<\/code><\/pre>\n
In this example, the ‘page’ argument is filled with 50000 ‘A’ characters, which exceeds the buffer’s capacity and results in a buffer overflow<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
The vendor has released a patch to address this vulnerability<\/a>, and all affected users should apply this fix as soon as possible. Until the patch can be applied, users may also consider using a Web Application<\/a> Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation measures. In all cases, it is crucial to monitor network traffic for any signs of exploitation of this vulnerability<\/a>. It is also recommended to limit access to the affected<\/a> devices to trusted networks and users, reducing the risk of potential attacks.<\/p>\n","protected":false},"excerpt":{"rendered":"
