CVE-2026-42251 (GCVE-0-2026-42251)

Vulnerability from cvelistv5 – Published: 2026-06-01 13:22 – Updated: 2026-06-01 15:29

Title

Hard-coded credentials in KS-SOMED

Summary

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.

Severity

8.7 (High)
