CVE-2024-32292 identifies a command injection vulnerability in the Tenda W30E router firmware version 1.0.1.25(633). The vulnerability resides in the formexeCommand function, which processes the cmdinput parameter without adequate input validation or sanitization. This flaw allows an unauthenticated remote attacker to inject arbitrary operating system commands via specially crafted input to the cmdinput parameter. The vulnerability is remotely exploitable over the network without requiring user interaction or prior authentication, increasing its risk profile. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. Exploitation could allow attackers to execute arbitrary commands with the privileges of the affected process, potentially leading to full device compromise, network pivoting, data interception, or denial of service. The vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). As of the publication date, no patches or mitigations have been officially released by Tenda, and no exploits have been publicly observed in the wild. This vulnerability affects a widely deployed consumer-grade router model, which is often used in home and small office environments, potentially exposing many users to risk.

The impact of CVE-2024-32292 is significant for organizations and individuals using the Tenda W30E router. Successful exploitation allows remote attackers to execute arbitrary commands on the device without authentication, compromising device confidentiality, integrity, and availability. Attackers could gain control over the router, intercept or manipulate network traffic, deploy malware, or use the device as a foothold for lateral movement within internal networks. This could lead to data breaches, service disruptions, and further compromise of connected systems. The vulnerability's network accessibility and lack of required user interaction increase the likelihood of exploitation. Small businesses and home users relying on this router model are particularly vulnerable due to limited security monitoring and patch management capabilities. The absence of patches increases exposure time, potentially inviting targeted or opportunistic attacks.

Given the lack of an official patch, affected users should immediately implement compensating controls. These include isolating the vulnerable router from untrusted networks, disabling remote management interfaces if enabled, and restricting access to the router's administrative interface to trusted IP addresses only. Network segmentation should be employed to limit the router's access to critical systems. Monitoring network traffic for unusual command execution patterns or unexpected outbound connections can help detect exploitation attempts. Users should regularly check for firmware updates from Tenda and apply them promptly once available. As a longer-term measure, consider replacing the affected router with a model from a vendor with a strong security track record and timely patching practices. Employing network intrusion detection systems (NIDS) that can detect command injection attempts targeting routers may also provide early warning.
