The “Subscribe” feature in Ultimate Booking System Booking Core 1.7.0 is vulnerable to CSV formula injection. The input containing the excel formula is not being sanitized by the application. As a result when admin in backend download and open the csv, content of the cells are executed.

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.
