The linked parameters are used without proper validation. For the function `addToWhitelist()` from contract `OpenSkySettings`, there is no mechanism that prevents the parameters `name` and `symbol` from being an empty string. Also, no mechanism validates the parameters `minBorrowDuration` and `maxBorrowDuration`, this could lead to a scenario where the latter variable is lower than the former one.
