CVE-2024-57224 is a command injection vulnerability identified in the Linksys E7350 router firmware version 1.1.00.032. The vulnerability resides in the apcli_do_enr_pin_wps function, specifically through improper sanitization of the 'ifname' parameter. This flaw allows an unauthenticated remote attacker to inject and execute arbitrary system commands on the affected device. The vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command), indicating that user-supplied input is not properly validated before being passed to a system command. The CVSS v3.1 base score is 9.8, reflecting its critical nature with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality (C:H), integrity (I:H), and availability (A:H). This means an attacker can fully compromise the device remotely without any authentication or user action. The vulnerability could allow attackers to take control of the router, intercept or manipulate network traffic, disrupt network services, or use the device as a foothold for further attacks within the network. Currently, no patches or firmware updates are listed, and no exploits have been reported in the wild, but the high severity score indicates a significant risk once exploitation techniques become publicly available.

The impact of CVE-2024-57224 is severe for organizations using the Linksys E7350 router. Successful exploitation can lead to complete device compromise, allowing attackers to execute arbitrary commands with root privileges. This can result in unauthorized access to internal networks, interception or modification of sensitive data, disruption of network availability, and potential pivoting to other internal systems. The vulnerability threatens confidentiality, integrity, and availability simultaneously, making it a critical risk for enterprise, government, and home networks. Organizations relying on these routers for secure wireless connectivity or as part of their network infrastructure may face significant operational disruptions and data breaches. The lack of required authentication and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation once public exploits emerge. Additionally, compromised routers can be leveraged in botnets or for launching further attacks, amplifying the threat landscape.

Immediate mitigation should focus on network-level controls to reduce exposure. Administrators should isolate affected Linksys E7350 devices from untrusted networks and restrict remote management interfaces to trusted IP addresses only. Implement strict firewall rules to block unauthorized access to router management ports. Monitor network traffic for unusual activity indicative of exploitation attempts. Since no official patch is currently available, consider temporarily replacing or disabling vulnerable devices in critical environments. Once Linksys releases a firmware update addressing this vulnerability, prioritize prompt installation. Additionally, conduct regular security audits of network devices to identify and remediate similar vulnerabilities. Employ network segmentation to limit lateral movement if a device is compromised. Educate staff about the risks of unpatched network hardware and maintain an inventory of all deployed devices to ensure timely updates.
