VAR-201109-0170
Vulnerability from variot - Updated: 2023-12-18 12:45Heap-based buffer overflow in Progea Movicon / PowerHMI 11.2.1085 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long request. When the software runs the project, it will listen to the 12233 port to process the special \"EIDP\" protocol, and submit a special \"EIDP\" message (the field is too large) through the WEB service to crash the service program. Movicon is an Italian HMI/SCADA software. When the software runs the project, it will listen to port 808 to receive the HTTP request. The server incorrectly processes the negative Content-Length field to trigger the heap-based buffer overflow. The memory can be destroyed by \"memcpy(heap_buffer, input, content_length_size)\". In addition, submitting an incoming HTTP request containing 8192 bytes can trigger a heap-based overflow. Movicon is prone to multiple heap-based buffer-overflow vulnerabilities and a denial-of-service vulnerability. Movicon 11.2 Build 1085 is vulnerable; other versions may also be affected
