CVE-2016-4087

Status: ModifiedHigh (8.1)—

Huawei S12700 switches with software before V200R008C00SPC500 and S5700 switches with software before V200R005SPH010, when the debug switch is enabled, allows remote attackers to cause a denial of service or execute arbitrary code via crafted DNS packets.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
