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.

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.

Dell BIOS versions contain an Insecure Automated Optimization vulnerability. A local authenticated malicious user could exploit this vulnerability by sending malicious input via SMI to obtain arbitrary code execution during SMM.

Dell BIOS versions contain a stack-based buffer overflow vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI to bypass security checks resulting in arbitrary code execution in SMM.

Dell BIOS contains a race condition vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI in order to bypass security checks during SMM.

Dell BIOS versions contain an Improper Authentication vulnerability. A locally authenticated malicious user could potentially exploit this vulnerability by sending malicious input to an SMI in order to bypass security controls.

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.

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 BIOS contains an improper input validation vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

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.

Affected Dell Client platforms contain a BIOS Setup configuration authentication bypass vulnerability in the pre-boot Intel Rapid Storage Response Technology (iRST) Manager menu. An attacker with physical access to the system could perform unauthorized changes to the BIOS Setup configuration settings without requiring the BIOS Admin password by selecting the Optimized Defaults option in the pre-boot iRST Manager.

Dell Client Consumer and Commercial Platforms contain an Arbitrary File Overwrite Vulnerability. The vulnerability is limited to the Dell Firmware Update Utility during the time window while being executed by an administrator. During this time window, a locally authenticated low-privileged malicious user could exploit this vulnerability by tricking an administrator into overwriting arbitrary files via a symlink attack. The vulnerability does not affect the actual binary payload that the update utility delivers.
