Summary
A vulnerability in the REST API endpoints of Cisco Nexus Dashboard and Cisco Nexus Dashboard...
A vulnerability in the REST API endpoints of Cisco Nexus Dashboard and Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to view sensitive information or upload and modify files on an affected device.
This vulnerability exists because of missing authorization controls on some REST API endpoints. An attacker could exploit th vulnerability by sending crafted API requests to an affected endpoint. A successful exploit could allow the attacker to perform limited Administrator functions, such as accessing sensitive information regarding HTTP Proxy and NTP configurations, uploading images, and damaging image files on an affected device.
Impact
CVE-2025-20348 has a CVSS score of 5.0 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-20348? CVE-2025-20348 is a medium-severity security vulnerability. No fixed version is listed yet.
- How severe is CVE-2025-20348? CVE-2025-20348 has a CVSS score of 5.0 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Is there a fix for CVE-2025-20348? No fixed version is listed for CVE-2025-20348 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-20348 exploitable, and should I be worried? Whether CVE-2025-20348 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-20348 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
