CVE-2026-9508
Suprema BioStar 2 versions 2.9.3 through 2.9.11 can expose backup ZIP files to anyone on the network because the backup path is allowed to be set inside the NGINX webroot. This misconfiguration lets an attacker download sensitive backups without authentication.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Suprema BioStar 2 2.9.3–2.9.11, typically used by security‑system administrators who configure backup locations.
Real-world impact
An attacker can retrieve backup archives that contain confidential data, potentially enabling server impersonation, unauthorized database access, and lateral movement within the network.
Why this severity
The CVSS score of 10 reflects that the flaw is exploitable over the network, requires no authentication, and can compromise confidentiality, integrity, and availability of highly sensitive data.
What to do about it
- ›Ensure backup files are not stored in the NGINX webroot or adjust permissions so they are not publicly accessible.
