Description

Use of hard-coded credentials in Klinika XP and KlinikaXP Insertino allowed an unauthorized attacker access to several internal services. Critically, this included access to the FTP server that hosted the application's update packages. The attacker with these credentials could upload a malicious update file, which then may have been distributed and installed on client machines as a legitimate update. This issue affects KlinikaXP: before 5.39.01.01. and KlinikaXP Insertino before 3.1.0.1 Beside removing the hardcoded credentials from the code, previously exposed credentials were also rotated preventing further attack attempts.

Affected products

BRI KlinikaXP: before 5.39.01.01 — fixed in 5.39.01.01
BRI KlinikaXP Insertino: before 3.1.0.1 — fixed in 3.1.0.1
