CVE-2024-46891
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 SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly restrict the size of generated log files. This could allow an unauthenticated remote attacker to trigger a large amount of logged events to exhaust the system's resources and create a denial of service condition.
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 confidenceSINEC INS versions prior to V1.0 SP2 Update 3 lack proper log file size restrictions, allowing unauthenticated remote attackers to trigger excessive logging events that exhaust system resources and cause denial of service.

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 SINEC INS installation and versionLocate the SINEC INS installation directory (typically under Siemens programs) and check for version information in version files, about dialog, or system information within the application interfaceAffected if The installed version cannot be determined or is listed as any version prior to V1.0 SP2 Update 3 (including base version 1.0 and any prior releases)
-
Compare installed version to safe baselineCompare your identified version string against the fixed version V1.0 SP2 Update 3 - check if your version number is lower, or if it shows 1.0 without the SP2 Update 3 designationAffected if The installed version is any build or release prior to V1.0 SP2 Update 3, or the version shows only 1.0 without subsequent service pack and update releases
-
Verify logging functionality is activeCheck if SINEC INS logging features are enabled by examining the configuration files or application settings related to logging, audit trails, or event recordingAffected if Logging is enabled and the version is prior to V1.0 SP2 Update 3 - the combination of enabled logging with a vulnerable version means the resource exhaustion condition can be triggered
Your environment is affected if SINEC INS is installed with any version prior to V1.0 SP2 Update 3 and logging is enabled, as the lack of log file size restrictions in these versions allows denial of service through excessive logging.

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 · scopedUpdate SINEC INS to version V1.0 SP2 Update 3 or later to receive the patch that implements proper log file size controls and rotation.
V1.0 SP2 Update 3
- Obtain SINEC INS V1.0 SP2 Update 3 from Siemens Industry Online Support (https://support.industry.siemens.com/)
- Create a backup of the current SINEC INS configuration and data
- Stop the SINEC INS service before applying the update
- Install or apply the V1.0 SP2 Update 3 patch following the Siemens installation documentation
- Start the SINEC INS service and verify it runs correctly
- Verify the log file size restrictions are now properly enforced
