Beckhoff Automation vulnerabilities and threats

A low privileged remote attacker may be able to disclose confidential information from the memory of a privileged process by sending specially crafted calls to the Device Manager web service that cause an out-of-bounds read operation under certain circumstances due to ASLR and thereby potentially copy confidential information into a response.

A local low privileged attacker can bypass the authentication of the Device Manager user interface, allowing them to perform privileged operations and gain administrator access.

A low privileged remote attacker can execute arbitrary code by sending specially crafted calls to the web service of the Device Manager or locally via an API and can cause integer overflows which then may lead to arbitrary code execution within privileged processes.

An high privileged remote attacker can inject arbitrary content into the custom CSS field on the affected devices due to improper neutralization of input during web page generation ('Cross-site Scripting').
