Dell PowerEdge Server BIOS and Dell Precision Rack BIOS contain an improper privilege management security vulnerability. An unauthenticated local attacker could potentially exploit this vulnerability, leading to privilege escalation.

Dell PowerEdge Server BIOS and Dell Precision Rack BIOS contain an Improper SMM communication buffer verification vulnerability. A local low privileged attacker could potentially exploit this vulnerability leading to out-of-bound read/writes to SMRAM.

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.

Dell PowerEdge Server BIOS and Dell Precision Rack BIOS contain an improper parameter initialization vulnerability. A local low privileged attacker could potentially exploit this vulnerability to read the contents of non-SMM stack memory.

Dell G7 17 7790 BIOS versions prior to 1.13.2 contain a UEFI BIOS Boot Services overwrite vulnerability. A local attacker with access to system memory may exploit this vulnerability by overwriting the EFIBOOTSERVICES structure to execute arbitrary code in System Management Mode (SMM).

Select Dell Client Commercial and Consumer platforms support a BIOS password reset capability that is designed to assist authorized customers who forget their passwords. Dell is aware of unauthorized password generation tools that can generate BIOS recovery passwords. The tools, which are not authorized by Dell, can be used by a physically present attacker to reset BIOS passwords and BIOS-managed Hard Disk Drive (HDD) passwords. An unauthenticated attacker with physical access to the system could potentially exploit this vulnerability to bypass security restrictions for BIOS Setup configuration, HDD access and BIOS pre-boot authentication.
