Overview
The security vulnerability CVE-2025-7418 is a critical issue found in the Tenda O3V2 1.0.0.12(3880) which can potentially lead to a system compromise or data leakage. This vulnerability affects the function fromPingResultGet of the file /goform/setPing of the component httpd. The severity of this vulnerability, based on its CVSS score, makes it a high-priority issue for any organization utilizing this product.
This vulnerability matters because it allows potential attackers to manipulate the ‘destIP’ argument, causing a stack-based buffer overflow. This type of attack can cause the application to crash, execute arbitrary code, or even allow unauthorized access to sensitive data. What’s worse is that this exploit can be conducted remotely, making it a significant threat to the security of any systems running the affected software.

How the Exploit Works
The vulnerability lies within the fromPingResultGet function of the /goform/setPing file. By manipulating the ‘destIP’ argument, an attacker can cause a stack-based buffer overflow. This overflow can overwrite the application’s stack, potentially allowing for execution of arbitrary code or causing the application to crash. This attack can be initiated remotely over a network, making it even more dangerous.
Conceptual Example Code
A conceptual example of how this vulnerability could be exploited might look something like this:
POST /goform/setPing HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
destIP=192.168.1.1%00[buffer overflow payload]In this example, the attacker sends a specially crafted POST request to the vulnerable endpoint. The ‘destIP’ argument is manipulated with a buffer overflow payload, which triggers the vulnerability.
Recommended Mitigation
The best way to mitigate this vulnerability is to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help to detect and prevent potential exploitation attempts. Always ensure that your systems are up-to-date with the latest security patches, and consider implementing a robust cybersecurity strategy that includes regular vulnerability scanning and patch management.
