CVE-2024-34057
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 · uneditedTriangle Microworks TMW IEC 61850 Client source code libraries before 12.2.0 lack a buffer size check when processing received messages. The resulting buffer overflow can cause a crash, resulting in a 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 · high confidenceTriangle Microworks TMW IEC 61850 Client libraries before version 12.2.0 contain a buffer overflow vulnerability due to missing buffer size validation when processing received IEC 61850 protocol messages. An attacker can send specially crafted messages to trigger the overflow, causing the client application to crash and resulting in 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 Triangle Microworks IEC 61850 library versionSearch for TMW IEC 61850 library files in your application or system (common file patterns: tmw61850, IEC61850, lib61850). Check version information in library headers, manifest files, or product documentation. On Windows, examine DLL properties; on Linux, check with 'strings' or 'ldd' on linked binaries.Affected if The installed library version is below 12.2.0
-
Check Siemens Sicam A8000 firmware versionAccess the Sicam A8000 web interface or console and navigate to System Information or Firmware version section. Alternatively, check via SNMP or the device management interface.Affected if Firmware version is below 05.30
-
Check Siemens Sicam SCC firmware versionAccess the Sicam SCC management interface or check firmware version through the system information panel in the control system software.Affected if Firmware version is below 10.0
-
Check Siemens Sicam EGS firmware versionAccess the Sicam EGS device management interface or check firmware version through the system information section.Affected if Firmware version is below 05.30
-
Check Siemens Sicam S8000 firmware versionAccess the Sicam S8000 web interface or console and navigate to System Information or Firmware version section.Affected if Firmware version is below 05.30
-
Check Siemens Sitipe AT versionExamine the installed Sitipe AT software version through the product documentation or system information.Affected if Any version of Siemens Sitipe AT is in use (all versions are affected)
You are affected if you use any Triangle Microworks IEC 61850 library version below 12.2.0, or any Siemens Sicam product firmware below the specified thresholds, or any version of Siemens Sitipe AT, AND your system processes IEC 61850 protocol messages from network sources.

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 · scoped05.3010.012.2.0
Upgrade to TMW IEC 61850 Client library version 12.2.0 or later which implements proper buffer size checking. Since this is a library-level fix, identify all deployments and applications using the vulnerable library versions and replace them with the patched version.
IEC 61850 Source Code Library version 12.2.0 or later
- 1. Identify all deployments of Triangle Microworks TMW IEC 61850 Client source code libraries in your environment
- 2. Check the current version of the library in each deployment
- 3. If the version is below 12.2.0, obtain the updated library version 12.2.0 or later from Triangle Microworks (trianglemicroworks.com)
- 4. Integrate the updated library into your application following vendor integration documentation
- 5. Redeploy the updated application to all affected systems
- 6. For Siemens products (Sicam A8000, Sicam SCC, Sicam EGS, Sicam S8000): contact Siemens for firmware updates addressing this vulnerability
- 7. For Sitipe AT (all versions): contact the vendor for remediation guidance
