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

CVE-2025-6110 is a critical vulnerability found in Tenda FH1201 1.2.0.14(408), a widely-used router firmware. This vulnerability, identified in an unknown component of the file \/goform\/SafeMacFilter, can lead to a stack-based buffer overflow. The exploit can be initiated remotely, putting countless systems at risk of unauthorized access<\/a>, compromise, or data leakage. Given the widespread use of Tenda FH1201, the impact of this vulnerability<\/a> is far-reaching and presents a significant risk to both individual and corporate users.<\/p>\n

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

CVE ID: CVE-2025-6110
\nSeverity: Critical (CVSS: 8.8)
\nAttack Vector: Remote Network<\/a>
\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(408)<\/p>\n

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

The vulnerability is triggered by manipulating the ‘page<\/a>‘ argument in the \/goform\/SafeMacFilter file. This manipulation can cause the system to overflow the buffer<\/a>, a common programming error where more data is written into a block of memory, or buffer, than it can hold. In this case, the overflow can corrupt relevant memory and potentially allow an attacker to execute arbitrary code<\/a> or cause a denial of service (DoS).<\/p>\n

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

Here is a conceptual example of a malicious HTTP POST request that could exploit this vulnerability:<\/p>\n

POST \/goform\/SafeMacFilter HTTP\/1.1\nHost: target_router_IP\nContent-Type: application\/x-www-form-urlencoded\npage=%s%s%s%s%s... [overly long string]<\/code><\/pre>\n
In this example, the attacker sends a request to the \/goform\/SafeMacFilter endpoint with a manipulated ‘page’ argument. The ‘page’ argument contains a string that is longer than the buffer can handle, causing a buffer overflow<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
The best way to mitigate this vulnerability<\/a> is to apply the patch provided by the vendor as soon as it becomes available. As a temporary measure, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and block attempts to exploit this vulnerability<\/a>. Regularly updating and patching your systems can also reduce the risk of being affected by such vulnerabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
