Technical Analysis

CVE-2025-45487 is a command injection vulnerability identified in the Linksys E5600 router, specifically in version 1.1.0.26. The flaw exists within the runtime.InternetConnection function, which likely handles aspects of the device's internet connectivity status or configuration. Command injection vulnerabilities (classified under CWE-77) allow an attacker to execute arbitrary commands on the underlying operating system by injecting malicious input into a vulnerable function that improperly sanitizes or validates user-supplied data. This vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The vector metrics specify that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), making it relatively easy to exploit. The impact affects confidentiality and integrity but not availability, meaning an attacker could potentially access sensitive information or alter device behavior but not cause denial of service. No known exploits are currently reported in the wild, and no patches have been linked yet. Given the nature of home and small office routers like the Linksys E5600, exploitation could lead to unauthorized access to network traffic, device configuration manipulation, or pivoting into internal networks. The lack of authentication requirement and remote exploitability make this a significant risk if devices are exposed to untrusted networks or the internet without proper protections.

Potential Impact

For European organizations, especially small businesses and home offices relying on Linksys E5600 routers, this vulnerability poses a risk of unauthorized command execution on network gateway devices. Exploitation could lead to interception or manipulation of network traffic, potentially exposing sensitive corporate data or credentials. Integrity compromise could allow attackers to alter router configurations, redirect traffic, or install persistent backdoors, facilitating further network intrusion. While large enterprises may use more robust network equipment, smaller entities and remote workers using consumer-grade routers are vulnerable. This could undermine organizational security postures, especially in sectors handling sensitive personal or financial data under GDPR regulations. Additionally, compromised routers could be leveraged as part of botnets or for launching attacks against other targets, increasing the broader threat landscape within Europe.

Mitigation Recommendations

1. Immediate network segmentation: Isolate Linksys E5600 devices from critical internal networks to limit potential lateral movement if compromised. 2. Disable remote management interfaces exposed to the internet to prevent external exploitation. 3. Monitor network traffic for unusual patterns indicative of command injection attempts or unauthorized configuration changes. 4. Apply any available firmware updates from Linksys promptly once a patch is released. In the absence of patches, consider temporary replacement with alternative devices not affected by this vulnerability. 5. Implement strict firewall rules to restrict inbound and outbound traffic to and from the router, minimizing exposure. 6. Educate users on the risks of exposing consumer routers directly to the internet and encourage use of VPNs or secure tunnels for remote access. 7. Regularly audit router configurations and logs to detect anomalies early. 8. Engage with Linksys support channels to obtain timelines for patch releases and coordinate vulnerability disclosure.
