| Proprietary Code CVE(s) | Description | CVSSBase Score | CVSS Vector String |
| CVE-2021-21502 | Dell PowerScale OneFS versions 8.1.0 – 9.1.0 contain a "use of SSH key past account expiration" vulnerability. A user on the network with the ISI_PRIV_AUTH_SSH RBAC privilege that has an expired account may potentially exploit this vulnerability, giving them access to the same things they had before account expiration. This may by a high privileged account and hence Dell recommends customers upgrade at the earliest opportunity. | 9.8 | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
| CVE-2020-26196 | Dell EMC PowerScale OneFS versions 8.1.0-9.1.0 contain a Backup/Restore Privilege implementation issue. A user with the BackupAdmin role may potentially exploit this vulnerability resulting in the ability to write data outside of the intended file system location. | 5.5 | CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N |
| CVE-2020-26195 | Dell EMC PowerScale OneFS versions 8.1.2 – 9.1.0 contain an issue where the OneFS SMB directory auto-create may erroneously create a directory for a user. A remote unauthenticated attacker may take advantage of this issue to slow down the system. | 5.3 | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L |
| CVE-2020-26194 | Dell EMC PowerScale OneFS versions 8.1.2 and 8.2.2 contain an Incorrect Permission Assignment for a Critical Resource vulnerability. This may allow a non-admin user with either ISI_PRIV_LOGIN_CONSOLE or ISI_PRIV_LOGIN_SSH privileges to exploit the vulnerability, leading to compromised cryptographic operations. | 7.0 | CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE-2020-26193 | Dell EMC PowerScale OneFS versions 8.1.0 - 9.1.0 contain an improper input validation vulnerability. A user with the ISI_PRIV_CLUSTER privilege may exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying OS, with the privileges of the vulnerable application. | 7.8 | CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE-2020-26192 | Dell EMC PowerScale OneFS versions 8.2.0 - 9.1.0 contain a privilege escalation vulnerability. A non-admin user with either ISI_PRIV_LOGIN_CONSOLE or ISI_PRIV_LOGIN_SSH may potentially exploit this vulnerability to read arbitrary data, tamper with system software or deny service to users. Note: No non-admin users or roles have these privileges by default. |
7.8 | CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE-2020-26191 | Dell EMC PowerScale OneFS versions 8.1.0 - 9.1.0 contain a privilege escalation vulnerability. A user with ISI_PRIV_JOB_ENGINE may use the PermissionRepair job to grant themselves the highest level of RBAC privileges thus being able to read arbitrary data, tamper with system software or deny service to users. | 7.8 | CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
