CVE-2026-42251

Use of hard-coded credentials in KS-SOMED allowed an unauthorized attacker access to 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 KS-SOMED with modules: KSPLUPDFTP.exe up to 30.00.00.056 and ANEKSKLIENT.EXE up to 29.00.02.026 Beside removing the hard-coded credentials from the code and changing the update process, access granted by previously exposed credentials was limited to read-only.

Este problema afecta a KS-SOMED con los módulos: KSPLUPDFTP.exe hasta la versión 30.00.00.056 y ANEKSKLIENT.EXE hasta la versión 29.00.02.026 Además de eliminar las credenciales codificadas del código y cambiar el proceso de actualización, el acceso otorgado por credenciales previamente expuestas se limitó a solo lectura.
