CVE-2025-7414 is a security vulnerability identified in the Tenda O3V2 device, specifically version 1.0.0.12(3880). The vulnerability resides in the 'fromNetToolGet' function within the '/goform/setPingInfo' endpoint of the device's HTTP daemon (httpd). The flaw allows an attacker to manipulate the 'domain' argument, which is not properly sanitized, leading to OS command injection. This means an attacker can inject arbitrary operating system commands remotely via crafted HTTP requests without requiring authentication or user interaction. The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:L, indicating low privileges but some level of access), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting partial compromise potential. The CVSS 4.0 score is 5.3, categorized as medium severity. Although the vulnerability is critical in nature due to command injection, the limited scope and partial impact reduce the overall severity. No public exploits are currently known in the wild, but the exploit details have been disclosed, increasing the risk of future exploitation. The lack of available patches or mitigation links indicates that affected users must rely on other defensive measures until an official fix is released.

For European organizations using Tenda O3V2 devices, this vulnerability poses a risk of unauthorized remote command execution, potentially allowing attackers to execute arbitrary commands on the device. This could lead to partial compromise of device confidentiality, integrity, and availability, such as unauthorized access to network configurations, disruption of network services, or pivoting to internal networks. Given that Tenda devices are often used in small to medium business environments and possibly in home office setups, the impact could extend to critical network infrastructure if these devices serve as gateways or routers. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise or widespread disruption without additional factors. However, the public disclosure of the exploit increases the urgency for European organizations to assess their exposure and implement mitigations promptly to prevent potential attacks that could disrupt business operations or leak sensitive information.

1. Immediate network segmentation: Isolate Tenda O3V2 devices from critical network segments to limit potential lateral movement if compromised. 2. Access control: Restrict remote management access to the device's HTTP interface using firewall rules or VPNs, ensuring only trusted IPs can reach the management interface. 3. Input filtering: If possible, implement web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block command injection patterns targeting the '/goform/setPingInfo' endpoint. 4. Monitoring and logging: Enable detailed logging on Tenda devices and network perimeter devices to detect suspicious requests or unusual command execution patterns. 5. Vendor engagement: Contact Tenda support to inquire about patches or firmware updates addressing this vulnerability and apply them as soon as they become available. 6. Device replacement: For high-risk environments, consider replacing affected devices with alternatives that have a stronger security track record until a patch is released. 7. User education: Inform network administrators about the vulnerability and the importance of restricting access and monitoring affected devices.
