CVE-2025-7415: Command Injection in Tenda O3V2
A vulnerability, which was classified as critical, has been found in Tenda O3V2 1.0.0.12(3880). This issue affects the function fromTraceroutGet of the file /goform/getTraceroute of the component httpd. The manipulation of the argument dest leads to command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
AI Analysis
Technical Summary
CVE-2025-7415 is a command injection vulnerability identified in the Tenda O3V2 device, specifically version 1.0.0.12(3880). The flaw exists in the HTTP daemon component, within the /goform/getTraceroute endpoint, in the fromTraceroutGet function. The vulnerability arises from improper sanitization of the 'dest' argument, which is used in a system command context. An attacker can remotely manipulate this parameter to inject arbitrary commands that the device executes with elevated privileges. This can lead to unauthorized command execution on the device, potentially allowing attackers to take full control, disrupt device functionality, or pivot into internal networks. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although the CVSS v4.0 score is 5.3 (medium severity), the nature of command injection typically implies a high risk due to the potential for full system compromise. No public exploits are currently known in the wild, but the exploit details have been disclosed, which may facilitate future attacks. The lack of available patches or mitigation guidance from the vendor further exacerbates the risk. Given that Tenda O3V2 devices are often used in small office/home office (SOHO) and enterprise wireless networking scenarios, exploitation could impact network availability, confidentiality, and integrity.
Potential Impact
For European organizations, this vulnerability poses a significant threat, especially for those deploying Tenda O3V2 devices in their network infrastructure. Successful exploitation could lead to unauthorized access to network devices, enabling attackers to intercept or manipulate network traffic, disrupt connectivity, or use the compromised device as a foothold for lateral movement within corporate networks. This is particularly concerning for critical infrastructure sectors, SMEs, and enterprises relying on Tenda hardware for wireless connectivity. The potential impact includes data breaches, operational disruption, and reputational damage. Additionally, given the remote exploitability without authentication, attackers can target exposed devices over the internet or within internal networks without user intervention. The medium CVSS score may underestimate the real-world risk, as command injection vulnerabilities often lead to critical consequences. European organizations with limited security monitoring or outdated device inventories are at higher risk.
Mitigation Recommendations
Organizations should immediately inventory their network devices to identify any Tenda O3V2 units running the affected firmware version 1.0.0.12(3880). Until an official patch is released, network administrators should restrict access to the device management interfaces by implementing network segmentation and firewall rules to limit exposure to trusted management networks only. Disabling remote management features and blocking inbound traffic to the /goform/getTraceroute endpoint can reduce attack surface. Monitoring network traffic for unusual traceroute requests or command injection patterns may help detect exploitation attempts. Employing intrusion detection/prevention systems (IDS/IPS) with custom signatures targeting this vulnerability is recommended. Organizations should engage with Tenda support channels to obtain firmware updates or advisories. Additionally, consider replacing vulnerable devices with more secure alternatives if patching is not feasible. Regularly updating device firmware and applying security best practices for IoT and network equipment management are critical to prevent exploitation.
