I can recommend looking at the following Community Article on how to fix CWE 73 flaws: https://community.veracode.com/s/article/how-do-i-fix-cwe-73-external-control-of-file-name-or-path-in-java (please note you must be logged in to the Community with a customer account).
Though it has Java examples the same applies for .NET.
Please note that System.IO.Path.GetInvalidPathChars() does not remove the security risk of an attacker being able to manipulate file paths as it only verifies that there are not invalid characters in the path (something like ../ which an attacker could use are valid characters and will not be blocked).
Thank you,
Boy Baukema
Thanks for your response. But it seems that the article has no content.
See screenshot below. I can only see the title.
Ah, sorry, thank you for letting me know! Looks like there is a problem with the access, I'll ask a Community administrator and let you know when it is available.
Hi,
I have the same issue with accessing the article link, could you please also let me know once this is resolved.
Thanks,
Martin
