How the CVE Works
The vulnerability (CVE-2025-5441) in Linksys RE6500, RE6250, RE6300, RE6350, RE7000, and RE9000 routers stems from improper input validation in the `setDeviceURL` function within /goform/setDeviceURL. An attacker can inject malicious OS commands via the `DeviceURL` parameter, leading to remote code execution. The flaw is exploitable without authentication, allowing attackers to manipulate device settings, execute arbitrary commands, or compromise the router. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) highlights its network-based attack vector and high impact on confidentiality, integrity, and availability.
