CVE-2026-20168: Error Handling 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 retrieve files that they do not have permission to access. This vulnerability is due to insufficient file access checks. An attacker could exploit this vulnerability by submitting crafted input in the web-based management interface. A successful exploit could allow the attacker to read files that they are not authorized to access.
AI Analysis
Technical Summary
This vulnerability in Cisco IoT Field Network Director (IoT-FND) arises from insufficient file access validation in the web-based management interface. An authenticated attacker with low privileges can exploit this by submitting specially crafted input to read files they should not have access to. The issue affects a broad range of versions from 4.1.0 through 4.12.1. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation allows an authenticated attacker with low privileges to read sensitive files beyond their authorization, potentially exposing confidential information. The vulnerability does not impact integrity or availability. There are no known active exploits 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 web-based management interface to trusted users only and monitor for suspicious activity. Do not rely on generic mitigations as the vulnerability specifically involves file access checks in the interface.
