Last modified
CVE-2021-21739 is a medium-severity vulnerability rated 4.6/10 on the CVSS scale. A ZTE's product of the transport network access layer has a security vulnerability. Because the system does not sufficiently verify the data reliability, attackers could replace an authenticated optical module on the equipment with an unauthenticated one, bypassing system authentication and detection, thus affecting signal transmission. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
