Weak Password Encoding in Dell BIOS Enables Privilege Escalation

Dell Client Platform BIOS contains a Weak Encoding for Password vulnerability. An unauthenticated attacker with physical access could potentially exploit this vulnerability, leading to Elevation of Privileges.

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 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 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 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 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.

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 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 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 may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

Dell Client BIOS contains a Buffer Overflow vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by manipulating an SMI to cause an arbitrary write during SMM.

Dell BIOS contains an Stack-Based Buffer Overflow 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 a Time-of-check Time-of-use vulnerability. A local authenticated malicious user could\u00a0potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI to gain arbitrary code execution on the system.

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.

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 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.

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 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.
