Class InvalidFileNameException
java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.RuntimeException
org.apache.tomcat.util.http.fileupload.InvalidFileNameException
- All Implemented Interfaces:
Serializable
This exception is thrown in case of an invalid file name.
A file name is invalid, if it contains a NUL character.
Attackers might use this to circumvent security checks:
For example, a malicious user might upload a file with the name
"foo.exe\0.png". This file name might pass security checks (i.e.
checks for the extension ".png"), while, depending on the underlying
C library, it might create a file named "foo.exe", as the NUL
character is the string terminator in C.
