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

A significant vulnerability, CVE-2025-55606, has been identified in the Tenda AX3 V16.03.12.10_CN. This vulnerability, a Buffer Overflow in the fromAdvSetMacMtuWan function via the serverName parameter, could potentially allow an attacker to compromise systems or leak sensitive data. As Tenda AX3 is a widely used product, this vulnerability has extensive implications and warrants immediate attention.<\/p>\n

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

CVE ID: CVE-2025-55606
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda AX3 | V16.03.12.10_CN<\/p>\n

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

The vulnerability is a Buffer Overflow in the fromAdvSetMacMtuWan function, which can be exploited via the serverName parameter. An attacker can send specially crafted data that, when processed by the fromAdvSetMacMtuWan function, causes the system to overwrite adjacent memory, potentially leading to arbitrary code execution or causing the system to crash.<\/p>\n

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

An example of how the vulnerability might be exploited is shown below. The “serverName” parameter is filled with a large amount of data, causing a buffer overflow:<\/p>\n

POST \/fromAdvSetMacMtuWan HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"serverName\": \"AAAAAAAAA...[continue until buffer overflow]\" }<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
The most effective mitigation strategy is to apply the official patch from the vendor. Until then, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking attempts to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
