OpenPLC vulnerabilities

Autonomy Logic OpenPLC 3 is susceptible to an improper neutralization of input during web page generation vulnerability when the web interface attempts to route the program based on a query string parameter with no encoding.

A path injection vulnerability exists in OpenPLC v3 (commit 2c82b0e79c53f8c1f1458eee15fec173400d6e1a). The binary compiled from glue_generator.cpp does not validate file path parameters from the command line, allowing an attacker to read arbitrary files.

A denial of service vulnerability exists in the ModbusTCP server functionality of OpenPLC _v3 a931181e8b81e36fadf7b74d5cba99b73c3f6d58. A specially crafted series of network connections can lead to the server not processing subsequent Modbus requests. An attacker can open a series of TCP connections to trigger this vulnerability.
