Dell Latitude 7420 Firmware any version

Dell BIOS contains a Stack based buffer overflow vulnerability. A local authenticated attacker could potentially exploit this vulnerability by using an SMI to send larger than expected input to a parameter to gain arbitrary code execution in SMRAM.

Dell BIOS contains a Credentials Management issue. A local authenticated malicious user may potentially exploit this vulnerability to gain access to sensitive information on an NVMe storage by resetting the BIOS password on the system via the Manageability Interface.

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 BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

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 a heap buffer overflow vulnerability. A local attacker with admin privileges could potentially exploit this vulnerability to perform an arbitrary write to SMRAM during SMM.

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 Client Platform BIOS contains a Stack-based Buffer Overflow Vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to arbitrary code execution.

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 BIOS contains a Signed to Unsigned Conversion Error vulnerability. A local authenticated malicious user with admin privileges could potentially exploit this vulnerability, leading to 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 UEFI BIOS https stack leveraged by the Dell BIOSConnect feature and Dell HTTPS Boot feature contains an improper certificate validation vulnerability. A remote unauthenticated attacker may exploit this vulnerability using a person-in-the-middle attack which may lead to a denial of service and payload tampering.

Dell BIOS contains an Improper Restriction of Excessive Authentication Attempts vulnerability. A local authenticated malicious administrator could exploit this vulnerability to bypass excessive NVMe password attempt mitigations in order to carry out a brute force attack.

Dell BIOS contains an Improper Restriction of Excessive Authentication Attempts vulnerability. A local authenticated malicious administrator could exploit this vulnerability to bypass excessive admin password attempt mitigations in order to carry out a brute force attack.

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 Out-of-Bounds Write vulnerability. A local authenticated malicious user with admin privileges could potentially exploit this vulnerability, leading to denial of service.

Dell BIOS contains an Improper Authorization vulnerability. An unauthenticated physical attacker may potentially exploit this vulnerability, leading to denial of service.

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.
