CVE-2023-36669 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Missing Authentication for a Critical Function within the Kratos NGC Indoor Unit (IDU) before 11.4 allows remote attackers to obtain arbitrary control of the IDU/ODU system. Any attacker with layer-3 network access to the IDU can impersonate the Touch Panel Unit (TPU) within the IDU by sending crafted TCP requests to the IDU.. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
