CVE-2020-6873

Estado: ModificadaMedia (5.3)—

A ZTE product has a DoS vulnerability. Because the equipment couldn’t distinguish the attack packets and normal packets with valid http links, the remote attackers could use this vulnerability to cause the equipment WEB/TELNET module denial of service and make the equipment be out of management. This affects: ZXR10 2800-4_ALMPUFB(LOW), all versions up to V3.00.40.
