Cisco published security advisories for two enterprise management platforms: a cross-site scripting (XSS) flaw in Cisco Catalyst SD-WAN Manager and a server-side request forgery (SSRF) flaw affecting Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights. The issues affect products used to centrally manage networking infrastructure, raising the risk that attackers could target administrative interfaces and backend request handling in high-value environments.
The advisories identify separate web-application security weaknesses in Cisco's network management stack, with one issue tied to malicious script execution in the SD-WAN management interface and the other to unauthorized server-side requests from Nexus Dashboard components. Organizations using these platforms should review Cisco's product advisories, determine affected deployments, and prioritize remediation or mitigations for exposed management systems.

dCERT issued advisories for **Cisco Catalyst SD-WAN Manager** and the **SD-WAN Controller**, warning of multiple security flaws affecting core SD-WAN management components. One advisory covers several vulnerabilities across the management platform and controller, indicating broader exposure in systems used to administer and orchestrate enterprise SD-WAN environments. A separate dCERT advisory identifies a **cross-site scripting (XSS)** vulnerability in Cisco Catalyst SD-WAN Manager, highlighting the risk that attackers could inject malicious script into the web-based management interface. Together, the notices point to security weaknesses in Cisco SD-WAN administrative infrastructure that could affect the confidentiality and integrity of management sessions and require prompt review and remediation by defenders.

Cisco disclosed a broad set of security flaws across enterprise products, including critical unauthenticated remote code execution, arbitrary command execution, and authentication bypass vulnerabilities affecting **Smart Software Manager On-Prem**, **Integrated Management Controller**, **Nexus Dashboard Fabric Controller**, and **Secure Firewall Management Center**. Additional high- and medium-severity issues impact **IOS XE** and other Cisco platforms, enabling denial of service, privilege escalation, arbitrary file write, server-side request forgery, secure boot bypass, sensitive information exposure, and cross-site scripting. Many of the vulnerabilities affect web-based management interfaces and network-facing services, raising the risk to remotely reachable administrative systems. One of the most severe issues, **`CVE-2026-20223`**, affects **Cisco Secure Workload** and allows an unauthenticated attacker to bypass REST API authentication and perform administrative actions. The flaw, tracked as **CWE-306** and rated **CVSS 10.0**, can expose configuration data, alter microsegmentation policies, and enable cross-tenant access with Site Admin-level impact in both SaaS and on-premises deployments. Cisco said no workaround is available and released fixes in versions **3.10.8.3** and **4.0.3.17**; reporting cited no known active exploitation or public proof-of-concept at the time.

Cisco disclosed two security vulnerabilities affecting enterprise products: an **unauthorized access flaw** in the **Cisco Nexus Dashboard Configuration Backup REST API** and an **authentication bypass flaw** in **Cisco Secure Web Appliance**. The Nexus Dashboard issue could expose backup-related functionality through the REST API without proper access controls, while the Secure Web Appliance flaw could allow an attacker to bypass authentication protections and gain access to affected systems. The advisories indicate separate weaknesses in Cisco infrastructure and security platforms that could undermine administrative boundaries and trusted access if left unpatched. Organizations using **Cisco Nexus Dashboard** or **Cisco Secure Web Appliance** should review Cisco's product advisories, identify affected deployments, and prioritize remediation to prevent unauthorized access to management or security enforcement functions.
