Affected devices do not properly sanitize contents of trace files.
This could allow an attacker to inject code through social engineering an authorized user, who has the function right "Read diagnostics", to import a specially crafted trace file.
The malicious trace file is insufficiently sanitized and malicious code could be executed in the clients browser session and trigger PLC operations via the webserver that the legitimate user is authorized to perform.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
