CVE-2026-20169: Improper Neutralization of Special Elements used in a Command ('Command Injection') in Cisco Cisco IoT Field Network Director (IoT-FND)
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.
AI Analysis
Technical Summary
This vulnerability in Cisco IoT Field Network Director (IoT-FND) affects multiple versions up to 4.12.1. It is caused by improper neutralization of special elements in user input within the web management interface, enabling command injection. An authenticated attacker with low privileges can exploit this by submitting crafted input, potentially allowing file manipulation and execution of limited commands on a remote router in user EXEC mode. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, scope change, and limited confidentiality and integrity impact without availability impact. There is no vendor advisory or patch information available at this time.
Potential Impact
Successful exploitation allows an authenticated attacker with low privileges to execute commands and manipulate files on a remote router via the IoT-FND management interface. This could lead to unauthorized access to sensitive information and limited control over router functions in user EXEC mode. The impact is limited to confidentiality and integrity with no availability impact reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Cisco IoT Field Network Director management interface to trusted users only and monitor for suspicious activity. Avoid exposing the management interface to untrusted networks.
