CVE-2022-23142

Management-site interruption via HTTP GET flood

Published Jul 18, 2022 · Updated Aug 3, 2024

Denial of service in ZTE ZXEN CG200 1.0.0P1N5_M and earlier allows remote attackers to interrupt its management website. ZTE has not disclosed the underlying implementation error; the documented trigger is a rapid burst of HTTP GET requests. Reachability requires adjacent-network access, and management-site unavailability is the only documented consequence.
