CVE-2023-5719: Redlion Crimson

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Redlion Crimson: before 3.2 (fixed in 3.2); version 3.2 only
