Summary
A vulnerability in Suprema BioStar 2 (versions 2.9.3 through 2.9.11) stems from incorrect permission settings on a critical resource, causing backup files to be publicly exposed when the administrator configures their path within the NGINX webroot. An attacker with network access can directly download backup ZIP files via ‘http(s)://[server]/download/…’ without authentication.
Risk Assessment
The risk for the organization includes exposure of highly sensitive information, which can lead to server impersonation, unauthorized access to databases, and lateral movement within the network.
Recommendation
It is recommended to immediately update Suprema BioStar 2 to version 2.9.12 or later, and to review and correct the NGINX configuration to ensure backup files are not publicly accessible.
