Critical Vulnerabilities in Tenda N300 Routers Expose Users to Remote Code Execution
Recent security analyses have uncovered severe vulnerabilities in Tenda N300 wireless routers and 4G03 Pro portable LTE devices. These flaws enable attackers to execute arbitrary commands with root privileges, posing significant risks to users. As of now, Tenda has not released patches to address these issues, leaving devices susceptible to exploitation.
Understanding the Vulnerabilities
The identified vulnerabilities stem from improper handling of user inputs within critical service functions on Tenda devices. Specifically, two command injection flaws have been documented:
1. CVE-2025-13207: This vulnerability affects Tenda 4G03 Pro devices running firmware versions up to and including v04.03.01.44. An authenticated attacker can exploit this flaw by sending specially crafted HTTP requests to TCP port 80, leading to remote code execution as the root user.
2. CVE-2024-24481: Impacting both Tenda N300 and 4G03 Pro devices with firmware versions up to v04.03.01.14, this vulnerability allows an authenticated attacker to execute arbitrary commands by sending crafted network requests to TCP port 7329.
Exploitation of these vulnerabilities grants attackers full control over the affected devices. Potential malicious activities include modifying router configurations, intercepting network traffic, deploying malware, or using the device as a launchpad for further network attacks. Given that routers serve as central hubs for network traffic, compromising them can have widespread implications for all connected devices and data.
Mitigation Strategies
In the absence of official patches from Tenda, users are advised to take the following precautionary measures:
– Device Replacement: For those in security-sensitive environments, consider replacing affected Tenda devices with routers from other vendors that have a strong track record of timely security updates.
– Limit Exposure: If immediate replacement isn’t feasible, minimize the device’s exposure by restricting network access and limiting its usage to essential functions only.
– Stay Informed: Regularly monitor Tenda’s official website and security advisories for potential firmware updates or patches.
The vulnerabilities were publicly disclosed on November 20, 2025. As of now, Tenda has not provided remediation measures, leaving users to implement the above strategies to safeguard their networks.
