Go to dashboardImproper input validation (CWE-20) in on-prem Arista VeloCloud Orchestrator, CVSS 3.1 10.0 / 4.0 9.5, actively exploited and in CISA KEV. An unauthenticated remote attacker with network access to the VCO web interface and the public part of a VeloCloud Edge authentication certificate can reach privileged internal functions on the VCO host. Only VCOs configured for certificate-based Edge authentication are exposed. Hosted and Dedicated VCO were already patched. A compromised VCO may give attackers access to Edge devices.
