CVE-2024-41464 is a stack-based buffer overflow vulnerability identified in the Tenda FH1201 router firmware version 1.2.0.14. The vulnerability arises from improper bounds checking of the mitInterface parameter in the ip/goform/RouteStatic HTTP endpoint. An attacker can send a specially crafted request to this endpoint, causing a buffer overflow on the stack, which may allow arbitrary code execution with the privileges of the router's web service process. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS v3.1 base score of 9.8 reflects the high impact on confidentiality, integrity, and availability, as successful exploitation could lead to full device compromise, enabling attackers to intercept or manipulate network traffic, disrupt network operations, or pivot into internal networks. The vulnerability is categorized under CWE-120 (Classic Buffer Overflow). As of the publication date, no official patches or firmware updates have been released by Tenda, and no public exploits have been observed in the wild. The affected firmware version is specifically 1.2.0.14, but the absence of detailed affected version data suggests users should verify their firmware versions carefully. Given the criticality and ease of exploitation, this vulnerability poses a significant risk to organizations relying on Tenda FH1201 routers for network connectivity.

The impact of CVE-2024-41464 is severe for organizations worldwide using the Tenda FH1201 router. Exploitation can lead to complete compromise of the router, allowing attackers to execute arbitrary code remotely without authentication. This can result in interception and manipulation of network traffic, unauthorized access to internal networks, disruption of network services, and potential lateral movement to other systems. The confidentiality of sensitive data traversing the network can be compromised, integrity of network configurations and data can be altered, and availability of network connectivity can be disrupted. Given the critical nature of routers as network gateways, this vulnerability could facilitate large-scale attacks, including espionage, data theft, or denial of service. The lack of patches increases the window of exposure, and the absence of required authentication lowers the barrier for attackers. Organizations in sectors with high reliance on secure network infrastructure, such as finance, healthcare, government, and critical infrastructure, face heightened risks.

1. Immediate network segmentation: Isolate Tenda FH1201 routers from critical network segments to limit potential lateral movement if compromised. 2. Disable remote management interfaces or restrict access to trusted IP addresses only to reduce exposure of the vulnerable endpoint. 3. Monitor network traffic for unusual requests targeting the ip/goform/RouteStatic endpoint, especially those containing suspicious mitInterface parameter values. 4. Employ Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block buffer overflow attack patterns against the router's HTTP interface. 5. Regularly audit and inventory network devices to identify all Tenda FH1201 routers and verify firmware versions. 6. Engage with Tenda support channels to obtain information on forthcoming patches or firmware updates and apply them promptly once available. 7. Consider temporary replacement or upgrade of vulnerable devices with models from vendors with active security support. 8. Educate network administrators about this vulnerability and ensure incident response plans include steps for router compromise scenarios.
