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

The cybersecurity landscape has witnessed yet another critical vulnerability – CVE-2025-9006 – that is affecting the Tenda CH22 1.0.0.1. This vulnerability is significant due to its potential for remote exploitation, leading to potential system compromise or data leakage. Primarily concerning the function formdelFileName of the file \/goform\/delFileName, this vulnerability is of high severity<\/a> based on its CVSS score of 8.8. In this post, we will dive deep into the technical aspects of this vulnerability<\/a>, its potential impact, and how to mitigate it.<\/p>\n

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

CVE ID: CVE-2025-9006
\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 CH22<\/a> | 1.0.0.1<\/p>\n

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

This exploit targets the function formdelFileName of the file<\/a> \/goform\/delFileName in Tenda CH22 1.0.0.1. The vulnerability arises from improper handling<\/a> of input data, leading to buffer overflow. An attacker can craft a malicious payload in such a way that it overflows the buffer, corrupts the memory<\/a>, and leads to unexpected behaviors, including potential remote code execution or system crashes. This vulnerability can be exploited remotely<\/a> without requiring any user interactions or privileges.<\/p>\n

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

Here is a conceptual example of how the vulnerability might be exploited. This example illustrates a HTTP POST request with a malicious payload that could potentially cause a buffer overflow<\/a>:<\/p>\n

POST \/goform\/delFileName HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"filename\": \"AAAAAAAAAAAAA...[continue till buffer overflow]...\"\n}<\/code><\/pre>\n
In the above example, the filename is filled with a large amount of data (‘A’s), causing a buffer overflow<\/a> in the formdelFileName function.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate the risk posed by this vulnerability<\/a>, Tenda users should apply the latest vendor-provided patches immediately. If the patch is not available, users may use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These solutions can help identify and block malicious activity associated with exploiting this vulnerability<\/a>. However, they should not be considered as a permanent fix.<\/p>\n","protected":false},"excerpt":{"rendered":"
