An Insecure Direct Object Reference (IDOR) vulnerability in the Xtivia Web Time and Expense (WebTE) interface used for Microsoft Dynamics NAV before 2017 allows an attacker to download arbitrary files by specifying arbitrary values for the recId and filename parameters of the /Home/GetAttachment function.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
