Dell Precision 7740 Firmware any version

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 Client Platform BIOS contains a Weak Authentication vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

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 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 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.

Dell Platform BIOS contains an Improper Null Termination vulnerability. A high privilege user with network access to the system could potentially send malicious data to the device in order to cause some services to cease to function.

Prior Dell BIOS versions contain an Improper Authentication vulnerability. An unauthenticated attacker with physical access to the system could potentially exploit this vulnerability by bypassing drive security mechanisms in order to gain access to the system.

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.

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 Client Platform BIOS contains an Out-of-bounds Write vulnerability in an externally developed component. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Information tampering.
