CWE-158Published: November 6, 2023· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official 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.
