Optiplex 5055 Firmware Security Vulnerabilities

CVE-2022-26858

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.

CVE-2022-26859

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.

CVE-2022-26860

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.

CVE-2022-26861

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.

CVE-2022-32483

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.

CVE-2022-32484

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.

CVE-2022-32485
