Vulnerability from cvelistv5 – Published: 2026-05-06 16:15 – Updated: 2026-05-06 17:26

Title

Cisco IoT Field Network Director Command Injection Vulnerability

Summary

A vulnerability in the web-based management interface of Cisco IoT Field Network Director could allow an authenticated, remote attacker with low privileges to access files and execute commands on a remote router. This vulnerability is due to insufficient input validation of user-supplied data. An attacker could exploit this vulnerability by submitting crafted input in the web-based management interface. A successful exploit could allow the attacker to create, read, or delete files and execute limited commands in user EXEC mode on a remote router.
