Select Dell Client Consumer and Commercial platforms include an issue that allows the BIOS Admin password to be changed through Dell's manageability interface without knowledge of the current BIOS Admin password. This could potentially allow an unauthorized actor, with physical access and/or OS administrator privileges to the device, to gain privileged access to the platform and the hard drive.
Dell Dock Firmware and Dell Client Platform contain an Improper Link Resolution vulnerability during installation resulting in arbitrary folder deletion, which could lead to Privilege Escalation or Denial of Service.
Select Dell Client Commercial and Consumer platforms contain a pre-boot direct memory access (DMA) vulnerability. An authenticated attacker with physical access to the system may potentially exploit this vulnerability in order to execute arbitrary code on the device.
Dell Client Consumer and Commercial platforms include an improper authorization vulnerability in the Dell Manageability interface for which an unauthorized actor, with local system access with OS administrator privileges, could bypass the BIOS Administrator authentication to restore BIOS Setup configuration to default values.
Dell BIOS contain a Time-of-check Time-of-use vulnerability in BIOS. A local authenticated malicious user with physical access to the system could potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI in order to gain arbitrary code execution on the system.
Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with admin privileges may potentially exploit this vulnerability to modify a UEFI variable, leading to denial of service and escalation of privileges
Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with admin privileges may potentially exploit this vulnerability in order to modify a UEFI variable.
Select Dell Client Commercial and Consumer platforms are vulnerable to an insufficient verification of data authenticity vulnerability. An authenticated malicious user may exploit this vulnerability in order to install modified BIOS firmware.
Dell BIOS contains an improper authentication vulnerability. A malicious user with physical access to the system may potentially exploit this vulnerability in order to modify a security-critical UEFI variable without knowledge of the BIOS administrator.
