CVE-2026-20174Patch(cisco / nexus_dashboard)

⚠️ **Vulnerability Alert:** Cisco Nexus Dashboard Insights Arbitrary File Write Vulnerability 📅 **Timeline:** Disclosure: 2026-04-01, Patch: 2026-04-01 🆔 **CVE-2026-20174** | 📊 CVSS: 4.9 (Medium 🟡) | 📈 EPSS: Not Available% 🛠️ **Exploit Maturity:** Not Available 📂 **Affected Versions:** Cisco Nexus Dashboard Insights 6.5 and earlier, Nexus Dashboard Release 3.1/3.2/4.1 (migrate to fixed releases), Nexus Dashboard Release 4.2+ 🔧 **Fixed Versions:** Nexus Dashboard Release 4.2+, Fixed releases per Cisco advisory 🫨 **Attack Vectors:** - Authenticated (administrative) remote upload of crafted metadata update file - Manual upload vector typical in air-gapped deployments (manual upload option exists for cloud-connected devices) 📝 **Summary:** An authenticated attacker with administrative access can upload a crafted metadata file that bypasses validation and writes arbitrary files to the OS as root, enabling privilege escalation and potential full system compromise. The manual upload option increases exposure in air‑gapped and some cloud-connected deployments—apply Cisco fixes immediately. 📈 **Impact Scope:** Arbitrary file writes as root leading to potential full system compromise of affected Nexus Dashboard Insights instances; risk is higher where manual metadata upload is enabled. 🛡️ **Recommended Actions:** - Upgrade affected systems to the fixed Nexus Dashboard / Nexus Dashboard Insights releases documented by Cisco immediately - Disable or tightly control manual metadata uploads and restrict to isolated maintenance windows - Enforce least-privilege for administrative accounts and rotate credentials - Monitor upload and system logs for suspicious metadata uploads and unexpected file writes - Test and validate upgrades in staging and contact Cisco TAC for assistance 🪢 **Related Resources:** - https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ndi-afw-rJuRC5dZ - https://bst.cloudapps.cisco.com/bugsearch/bug/CSCws40848 🏷 **Tags:** #Cybersecurity #Cisco #NexusDashboardInsights
