Biostar 2 Server
Monthly
Unauthenticated denial of service in Suprema BioStar 2 Server versions 2.9.8, 2.9.10, and 2.9.11 allows remote attackers to halt critical processes by sending HTTP POST requests to the '/api/migration' endpoint, taking access control readers offline until manual service or server restart. No public exploit identified at time of analysis, though SSVC flags the attack as automatable with partial technical impact. Because BioStar 2 governs physical access control, the outage cascades to door readers and downstream third-party integrations, elevating real-world impact beyond a typical web-app DoS.
Unauthenticated backup file disclosure in Suprema BioStar 2 server (versions 2.9.3 through 2.9.11) allows remote attackers to download sensitive backup ZIP archives directly via predictable '/download/' URLs when the administrator places the backup path inside the NGINX webroot. The exposed archives can contain database credentials and cryptographic material enabling server impersonation, database compromise, and lateral movement. No public exploit identified at time of analysis, but SSVC rates the flaw as automatable with total technical impact and CVSS 4.0 scores it 10.0.
