EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 71% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
