Cisco IoT Field Network Director Remote Device Denial of Service Vulnerability_CVE-2026-20167

{
    "lastseen": "",
    "description": "A vulnerability in the web-based management interface of Cisco IoT Field Network Director could allow an authenticated, remote attacker with low privileges to cause a DoS condition on a remotely managed router.\r\n\r\nThis vulnerability is due to improper error handling. An attacker could exploit this vulnerability by submitting crafted input to the web-based management interface. A successful exploit could allow the attacker to request unauthorized files from a remote router, causing the router to reload and resulting in a DoS condition.",
