CVE-2026-34473
HighSummary
Devices ZTE H8102E, H168N, H167A, H199A, H288A, H198A, H267A, H267N, H268A, H388X, H196A, H369A, H268N, H208N, H367N, H181A, and H196Q are vulnerable to an unauthenticated DoS attack. This can be triggered by sending an oversized application/x-www-form-urlencoded POST body, causing the management interface to become unresponsive until the device is rebooted.
Risk Assessment
An attacker can cause the router's management interface to become unavailable, potentially leading to service disruptions. The impact on devices with firmware prior to 2022 can be significant.
Recommendation
It is recommended to update the device firmware to versions released after March 23, 2021, to minimize the risk of DoS attacks. Additionally, monitoring traffic to the management interface for potential attack attempts is advised.

Original NVD description (English source)
Unauthenticated DoS in ZTE H8102E, H168N, H167A, H199A, H288A, H198A, H267A, H267N, H268A, H388X, H196A, H369A, H268N, H208N, H367N, H181A, and H196Q. A denial-of-service condition can be triggered against the router's web interface by sending an oversized application/x-www-form-urlencoded POST body. After triggering, the management interface may become unresponsive until the device is rebooted. This may affect any firmware version prior to 2022 (reporter observation). The supplier stated that devices are not vulnerable since 2021-03-23; operator firmware may vary.
