Triangle 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.
AnalysisAI
Triangle Microworks TMW IEC 61850 Client source code libraries before 12.2.0 lack a buffer size check when processing received messages. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. Triangle 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. Affected products include: Trianglemicroworks Iec 61850 Source Code Library, Siemens Sicam A8000 Firmware, Siemens Sicam Scc Firmware, Siemens Sicam Egs Firmware, Siemens Sicam S8000. Version information: before 12.2.0.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
