CVE-2026-42251
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUse 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceKS-SOMED contains hard-coded credentials embedded in KSPLUPDFTP.exe (up to 30.00.00.056) and ANEKSKLIENT.EXE (up to 29.00.02.026) that provide unauthorized access to the FTP server hosting application update packages. An attacker with these credentials could potentially upload malicious update files that would be distributed and installed on client machines as legitimate updates.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate KSPLUPDFTP.exe and determine its versionSearch for KSPLUPDFTP.exe in installation directories (commonly in program files or application data folders for KS-SOMED) and retrieve file properties to read the version number. Use PowerShell: Get-ChildItem -Path 'C:\' -Recurse -Filter 'KSPLUPDFTP.exe' -ErrorAction SilentlyContinue | Select-Object FullName, VersionInfoAffected if Version is 30.00.00.056 or lower (including any version up to 30.00.00.056)
-
Locate ANEKSKLIENT.EXE and determine its versionSearch for ANEKSKLIENT.EXE in installation directories and retrieve file properties to read the version number. Use PowerShell: Get-ChildItem -Path 'C:\' -Recurse -Filter 'ANEKSKLIENT.EXE' -ErrorAction SilentlyContinue | Select-Object FullName, VersionInfoAffected if Version is 29.00.02.026 or lower (including any version up to 29.00.02.026)
-
Verify update functionality is configured or activeCheck for configuration files or registry entries indicating the FTP update feature is enabled. Look for update server URLs, FTP connection settings, or scheduled tasks related to KS-SOMED or ANEKSKLIENT auto-update.Affected if The update feature is enabled, configured to connect to an update server, or scheduled to run automatically
-
Review update server configuration for hardcoded credentialsExamine configuration files, INI files, XML configs, or embedded settings within the executable that contain FTP server credentials (username/password). Search for strings like 'ftp://' or 'update' in config files in the application directory.Affected if Hardcoded FTP credentials (username and password) are found in configuration files or embedded within the application
You are affected if either KSPLUPDFTP.exe version 30.00.00.056 or lower OR ANEKSKLIENT.EXE version 29.00.02.026 or lower is present AND the FTP update feature is enabled or configured.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRemove all hard-coded credentials from the application code and implement secure credential management (e.g., environment variables, secure vault, or prompt-based authentication). Additionally, redesign the update distribution process to use secure, authenticated channels with integrity verification.
