3) Input validation error
EUVDB-ID: #VU57092
Risk: Medium
CVSSv3.1: 7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-03554
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to insufficient validation of user-supplied input in the restore file. A remote authenticated attacker can pass specially crafted input to the application and execute arbitrary code on the target system.
