CVE-2023-29401 Information

Description

The filename parameter of the Context.FileAttachment function is not properly sanitized. A maliciously crafted filename can cause the Content-Disposition header to be sent with an unexpected filename value or otherwise modify the Content-Disposition header. For example a filename of \setup.bat";x=.txt\ will be sent as a file named \setup.bat. If the FileAttachment function is called with names provided by an untrusted source this may permit an attacker to cause a file to be served with a name different than provided. Maliciously crafted attachment file name can modify the Content-Disposition header.
