CVE-2026-1958Network attack vector

Malicious update uploads via hard-coded FTP credentials

Published Mar 23, 2026 · Updated Mar 23, 2026

Hard-coded credentials in BRI Klinika XP before 5.39.01.01 and Insertino before 3.1.0.1 allow remote attackers to access internal services. Both applications embed reusable service credentials that authenticate to several back-end systems, including the FTP repository storing trusted update packages. No prior account is required; FTP access permits malicious update uploads, while client impact depends on the normal distribution and installation path.
