Proprietary Code CVEs Description CVSS Base Score CVSS Vector String
CVE-2021-21565 Dell PowerScale OneFS versions 9.1.0.3 and earlier contain a denial of service vulnerability. SmartConnect had an error condition that may be triggered to loop, using CPU and potentially preventing other SmartConnect DNS responses. 5.3 CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
CVE-2021-21553 Dell PowerScale OneFS versions 8.1.0-9.1.0 contain an Incorrect User Management vulnerability. Under some specific conditions, this can allow the CompAdmin user to elevate privileges and break out of Compliance mode. This is a critical vulnerability and Dell recommends upgrading at the earliest. 7.3 CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
CVE-2021-21562 Dell PowerScale OneFS contains an untrusted search path vulnerability. This vulnerability allows a user with (ISI_PRIV_LOGIN_SSH or ISI_PRIV_LOGIN_CONSOLE) and (ISI_PRIV_SYS_UPGRADE or ISI_PRIV_AUDIT) to provide an untrusted path. This untrusted path can lead to run resources that are not under the application’s direct control. 4.4 CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N
CVE-2021-21563 Dell PowerScale OneFS versions 8.1.2-9.1.0.x contain an Improper Check for Unusual or Exceptional Conditions in its auditing component. This allows an authenticated user with low-privileges to trigger a denial of service event. 6.5 CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
