Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Improper access control
EUVDB-ID: #VU57320
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:H/RL:O/RC:C]
CVE-ID: CVE-2021-39226
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions to database snapshots. Remote unauthenticated and authenticated users are able to view the snapshot with the lowest database key by accessing the literal paths: /dashboard/snapshot/:key, or /api/snapshots/:key. If the snapshot "public_mode" configuration setting is set to true (vs default of false), unauthenticated users are able to delete the snapshot with the lowest database key by accessing the literal path: /api/snapshots-delete/:deleteKey.
Regardless of the snapshot "public_mode" setting, authenticated users are able to delete the snapshot with the lowest database key by accessing the literal paths: /api/snapshots/:key, or /api/snapshots-delete/:deleteKey. The combination of deletion and viewing enables a complete walk through all snapshot data while resulting in complete snapshot data loss.
MitigationInstall updates from vendor's repository.
