Detailsinfo

A vulnerability was found in Cisco Nexus Dashboard and Nexus Dashboard Insights (version now known). It has been declared as critical. This vulnerability affects some unknown processing. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights could allow an unauthenticated, remote attacker to conduct a server-side request forgery (SSRF) attack through an affected device. This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by persuading an authenticated user of the device management interface to click a crafted link. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected device to an attacker-controlled server. The attacker could then execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.
