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

A critical vulnerability, identified as CVE-2025-8180, has been found in the Tenda CH22 1.0.0.1. This vulnerability targets the formdeleteUserName function of the file \/goform\/deleteUserName via the manipulation of the argument old_account, leading to a buffer overflow condition. This issue is especially troubling as it allows for remote<\/a> attacks, potentially leading to system compromise or data leakage. The exploit has already been publicly disclosed and may be in active use, making it a significant threat to any individual or organization using the affected version of the software.<\/p>\n

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

CVE ID: CVE-2025-8180
\nSeverity: Critical (CVSS: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, potential 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

The vulnerability occurs due to inadequate input validation<\/a> in the formdeleteUserName function of the \/goform\/deleteUserName file. This allows an attacker to manipulate the old_account argument, creating a buffer overflow<\/a> condition. This condition can allow the attacker to execute arbitrary code<\/a> on the system, which could potentially compromise the system or lead to unauthorized access to sensitive data.<\/p>\n

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

In a real-world example, an attacker might use a POST request to target the vulnerability<\/a>. The malicious request might look something like this:<\/p>\n

POST \/goform\/deleteUserName HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nold_account=<\/code><\/pre>\n
In this example, “ represents a string of data designed to trigger the buffer overflow<\/a> condition. This payload would be carefully crafted by the attacker to exploit the buffer overflow vulnerability<\/a>, potentially allowing the attacker to execute arbitrary code on the system.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The best course of action for mitigating this vulnerability<\/a> is to apply the vendor patch as soon as it becomes available. If applying the patch isn’t immediately possible, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can offer a temporary solution to mitigate the risk posed by this vulnerability<\/a>. It is also advisable to always be vigilant about the security of the system by regularly updating and patching the software<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
