CVE-2026-25569
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). An out-of-bounds write vulnerability exists in SICAM SIAPP SDK. This could allow an attacker to write data beyond the intended buffer, potentially leading to denial of service, or arbitrary code execution.
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 confidenceAn out-of-bounds write vulnerability exists in SICAM SIAPP SDK versions prior to V2.1.7. This memory corruption flaw allows an attacker to write data beyond the boundaries of an allocated buffer, which could corrupt memory and enable denial of service conditions or potentially achieve arbitrary code execution.

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 SICAM SIAPP SDK installationSearch for SDK files named 'SIAPP', 'sicam_siapp', or similar naming patterns in common installation directories such as C:\Program Files\Siemens, /opt/siemens, or application-specific directories. Also check the application's dependencies or third-party libraries folder.Affected if The SDK files are found on the system and the version is below V2.1.7 (or below version 2.17 as specified in the affected products range).
-
Identify SDK versionExamine version information in SDK DLL/SO files, version metadata files (e.g., version.txt, SIAPP_Version), or check product properties if the SDK includes an installer. Look for version strings in file properties or embedded resource sections.Affected if Version string shows a build or release number less than 2.1.7 or less than 2.17.
-
Check application dependenciesIf the SDK is embedded within a larger application, inspect the application's manifest, dependency configuration, or loaded modules to identify which version of the SICAM SIAPP SDK is being used at runtime.Affected if The application loads or references an SDK version prior to V2.1.7 (or < 2.17).
The environment is affected if the SICAM SIAPP SDK is present and its version is determined to be less than V2.1.7 (or less than version 2.17 as specified in the affected products range).

Upgrade SICAM SIAPP SDK to version V2.1.7 or later to remediate this vulnerability. Identify all deployments using the affected SDK versions and validate the upgrade in a staging environment before production deployment.
SICAM SIAPP SDK V2.1.7 or later
- Obtain SICAM SIAPP SDK version V2.1.7 or later from the Siemens cert-portal.siemens.com or official Siemens support channels
- Review the release notes and upgrade documentation provided with the new version
- Backup your current system configuration and data before proceeding with the upgrade
- Upgrade the SICAM SIAPP SDK installation to version V2.1.7 or later following the documented upgrade procedure
- Verify the upgrade was successful and test that the application functions correctly
- Deploy the updated version to production environments after successful testing
