Tiki 17.1 does not validate user input for special characters; consequently, a CSV Injection attack can open a CMD.EXE or Calculator window on the victim machine to perform malicious activity, as demonstrated by an =cmd| /C calc!A0 payload during User Creation.

Weakness

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.
