CVE-2022-32961
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 · uneditedHICOS’ client-side citizen digital certificate component has a stack-based buffer overflow vulnerability when reading IC card due to insufficient parameter length validation for token information. An unauthenticated physical attacker can exploit this vulnerability to execute arbitrary code, manipulate system data or terminate 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 confidenceHICOS client-side citizen digital certificate component contains a stack-based buffer overflow vulnerability when reading IC card data. The root cause is insufficient validation of parameter length for token information, allowing an unauthenticated attacker with physical access to the system to potentially execute arbitrary code, manipulate data, or 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 if HICOS client is installedLook for HICOS or Natural Person Credential Component in installed programs list (Control Panel > Programs and Features) or check for HiCOS-related processes runningAffected if HICOS client software is present on the system
-
Check installed HICOS versionRight-click the HICOS application icon, select Properties, and view the Version tab; or check the program's file version informationAffected if Version equals 3.0.3.30306, 3.0.3.30404, or 3.1.0.00002 exactly
-
Verify IC card reader is configuredCheck if the system has IC card reader drivers installed and the HICOS service is set to auto-start; look for smart card related services in Services.mscAffected if IC card reader is connected and HICOS service is running or configured to start automatically
-
Review access to IC card reading functionalityCheck whether the system allows unauthenticated or physical-access IC card reads without additional verification; examine HICOS security settings if accessibleAffected if Physical access to the system is not controlled and IC card reading feature is enabled without authentication requirements
You are affected if the HICOS Natural Person Credential Component Client is installed with version 3.0.3.30306, 3.0.3.30404, or 3.1.0.00002 and IC card reading functionality is enabled on a system with untrusted physical access.
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.
From vendor dataApply vendor-supplied patch from HICOS to address the parameter length validation; until patch is available, restrict physical access to systems handling IC card reads and monitor for anomalous behavior.
