MEDIUM 5.3EPSS 0.96%

Does this matter?

Lower severity and a low EPSS score (0.96%). Track it; it rarely justifies an emergency change on its own.

Description

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.
