CVE-2026-25570
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 · uneditedA vulnerability has been identified in SICAM SIAPP SDK (All versions < V2.1.7). The SICAM SIAPP SDK does not perform checks on input values potentially resulting in stack overflow. This could allow an attacker to perform code execution and denial of service.
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 · moderate confidenceThe SICAM SIAPP SDK versions prior to V2.1.7 lack proper input validation checks, allowing potentially malicious input values to trigger a stack overflow condition. This memory corruption vulnerability could enable an attacker to achieve arbitrary code execution or cause a denial of service on the affected system.

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.
-
Identify SICAM SIAPP SDK installationLocate the SICAM SIAPP SDK installation directory and check for version information files such as version.txt, About dialog, or SDK release notes. Common locations include C:\Program Files\Siemens\SICAM\SIAPP or similar installation paths.Affected if The installed version is found to be below V2.1.7 (or V2.17 if using three-digit versioning)
-
Verify SDK version in project referencesIf you have source code using this SDK, check the project references or dependency manifests (packages.config, .csproj, or similar) for the SICAM SIAPP SDK version number.Affected if The referenced SDK version is less than 2.1.7
-
Determine if external input is processedIdentify whether applications or services built with this SDK process external input from network sources, user inputs, or file imports that could reach the SDK's parsing functions.Affected if External or untrusted input is processed by code using this vulnerable SDK version
-
Check for input validation layerInspect application code that uses the SDK to determine if custom input validation or bounds checking is performed before passing data to SDK functions.Affected if No input validation layer exists and the SDK version is vulnerable
-
Audit SDK configuration filesReview any configuration files or settings related to the SICAM SIAPP SDK installation for security-related parameters or input handling settings.Affected if Configuration allows unrestricted input processing without validation
You are affected if your installed SICAM SIAPP SDK version is below V2.1.7 and your application processes external input that reaches SDK functions without additional validation.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped2.17
Upgrade to SICAM SIAPP SDK V2.1.7 or later which addresses the input validation vulnerability. If immediate patching is not possible, implement input bounds checking and validation routines before processing any external input.
SICAM SIAPP SDK V2.1.7
- 1. Navigate to the Siemens cert-portal website or official Siemens support channels to obtain the SICAM SIAPP SDK version 2.1.7
- 2. Verify the integrity of the downloaded package using checksums if provided
- 3. Backup your current project configurations and any custom implementations using the existing SDK
- 4. Uninstall or remove the current SICAM SIAPP SDK version
- 5. Install version 2.1.7 of the SICAM SIAPP SDK
- 6. Rebuild and recompile your application with the updated SDK
- 7. Test the application thoroughly to ensure functionality is maintained
- 8. Validate that input validation is now properly implemented in the updated SDK
