title: Red Lion Crimson Improper Neutralization of Null Byte or NUL Character
description:
The Crimson 3.2 Windows-based configuration tool allows users with administrative access to define new passwords for users and to download the resulting security configuration to a device. If such a password contains the percent (%) character, invalid values will be included, potentially truncating the string if a NUL is encountered. If the simplified password is not detected by the administrator, the device might be left in a vulnerable state as a result of more-easily compromised credentials. Note that passwords entered via the Crimson system web server do not suffer from this vulnerability.
