Summary
A ZTE product has a configuration error vulnerability. Because a certain port is open by default, an attacker can consume system processing resources by flushing a large number of packets to the port, and successfully exploiting this vulnerability could reduce system processing capabilities. This affects: ZXA10 C300M all versions up to V4.3P8.
