Although it is not possible to exploit this directly (e.g., adding a new user fails because \\n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \\r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that \"cat /etc/passwd\" shows a rogue user account.",
