CVE-2022-31812
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 SiPass integrated (All versions < V2.95.3.18). Affected server applications contain an out of bounds read past the end of an allocated buffer while checking the integrity of incoming packets. This could allow an unauthenticated remote attacker to 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 confidenceAn out-of-bounds read vulnerability exists in SiPass integrated server applications (all versions prior to V2.95.3.18) when checking the integrity of incoming network packets. The vulnerability allows an unauthenticated remote attacker to read past the end of an allocated buffer, potentially causing a denial of service condition.

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 installed SiPass integrated versionLocate the SiPass integrated application on the system and check its version information through the application's about dialog, installed programs list, or version file within the installation directoryAffected if The installed version is any release prior to V2.95.3.18
-
Verify SiPass network service statusCheck if the SiPass integrated server service is running and listening on network ports (typically TCP ports 443 or 8080 for SiPass web services)Affected if The SiPass server service is active and accepting network connections
-
Assess network exposureReview firewall rules and network configuration to determine if the SiPass server ports are accessible from untrusted network segmentsAffected if The SiPass network ports are exposed to untrusted or external networks without adequate filtering
A user is affected if their installed SiPass integrated version is below V2.95.3.18 AND the network service is running and accessible to potential attackers.

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 · scoped2.95.3.18
Upgrade SiPass integrated to version V2.95.3.18 or later to remediate this vulnerability. In the interim, network segmentation and firewall rules restricting access to the SiPass server application may reduce exposure.
V2.95.3.18
- Identify the current version of SiPass Integrated running in your environment
- Download SiPass Integrated version 2.95.3.18 or later from the official Siemens support portal (cert-portal.siemens.com)
- Follow Siemens' official upgrade procedure to update to version 2.95.3.18
- Verify the upgrade was successful by checking the version number
