1) Stack-based buffer overflow
EUVDB-ID: #VU25615
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-7007
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the web setting page IEEE802.1x setting page. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code or cause a denial of service (DoS) condition on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
