Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_gvret.cpp, the length field in GVRET binary data is not properly validated, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted GVRET frames.
AnalysisAI
Remote code execution in Open Vehicle Monitoring System 3 (OVMS3) version 3.3.005 allows network-based attackers to execute arbitrary code or crash the system without authentication. A buffer overflow in the GVRET CAN data parser (canformat_gvret.cpp) fails to validate length fields in binary frames, enabling memory corruption. …
