CVE-2026-7473: Arista EOS tunnel decapsulation validation flaw
Affected Arista EOS switches can forward unexpected tunnel traffic sent to a configured decapsulation IP. Arista specifies ACL mitigation, not a software upgrade; plan filters around shared-IP services and potentially disruptive TCAM changes.
CVE-2026-10520: Ivanti Sentry OS Command Injection Vulnerability
Ivanti Sentry command injection can permit unauthenticated root access when the appliance is unmanaged and vulnerable endpoints are externally reachable. Managed access controls limit exposure but do not establish a software fix; the fixed-build mapping remains unverified.
CVE-2026-20262: Cisco Catalyst SD-WAN Manager arbitrary file write
Authenticated attackers can create or overwrite files through Catalyst SD-WAN Manager path traversal. Preserve admin-tech and upload logs, install the branch-specific fix, and involve Cisco TAC when suspicious uploads or other indicators appear.
CVE-2025-67038: Lantronix EDS5000 Code Injection Vulnerability
Lantronix EDS5000 username-parameter injection can run commands as root. Record the model, hardware revision and firmware; available release notes describe upgrade constraints but do not establish a CVE-specific fixed build.
CVE-2026-34908: UniFi OS improper access control allows unauthorized system changes
UniFi OS access-control failures can allow unauthorized system changes from the network. Update the affected console or server and review its state and access logs; installing the fix does not reverse earlier changes.
CVE-2026-34909: UniFi OS path traversal
UniFi OS path traversal can expose underlying files to an attacker with network access. Apply the product-specific update and preserve access logs; the reviewed scope does not establish arbitrary file upload or placement.
CVE-2026-34910: UniFi OS input-validation flaw
UniFi OS input-validation failures can permit command injection from an attacker with network access. Match the exact console or server product to its fixed release, then review system and access logs for unexplained activity.
CVE-2026-20230: Cisco Unified Communications Manager Server-Side Request Forgery (SSRF) Vulnerability
Unified CM and Unified CM SME systems with WebDialer enabled face unauthenticated file writes that may later enable root escalation. Check actual service state, then select Cisco's update or assess temporary disablement's workflow impact.
CVE-2026-45659: SharePoint authenticated remote code execution
SharePoint code execution requires an authenticated attacker with at least Site Member permissions. CISA records ransomware-campaign use; apply edition-specific farm updates and preserve membership, IIS and endpoint evidence without assuming this farm was compromised.
CVE-2008-4128: Cisco IOS Cross-Site Request Forgery Vulnerability
Legacy Cisco IOS 12.4 request forgery can misuse a signed-in administrator's browser to issue commands. The linked retirement notice does not identify a fixed image; confirm a hardware-compatible supported migration and preserve management evidence.
