2) Improper Protection of Alternate Path

EUVDB-ID: #VU55590

Risk: Medium

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-20206

CWE-ID: CWE-424 - Improper Protection of Alternate Path

Exploit availability: No

Description

The vulnerability allows a remote user to compromise the affected system.

the vulnerability exists due to improper input validation.
