An issue was discovered in TrEEConfigDriver in Insyde InsydeH2O with kernel 5.0 through 5.5. It can report false TPM PCR values, and thus mask malware activity. Devices use Platform Configuration Registers (PCRs) to record information about device and software configuration to ensure that the boot process is secure. (For example, Windows uses these PCR measurements to determine device health.) A vulnerable device can masquerade as a healthy device by extending arbitrary values into Platform Configuration Register (PCR) banks. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023045 •

An issue was discovered in SystemFirmwareManagementRuntimeDxe in Insyde InsydeH2O with kernel 5.0 through 5.5. The implementation of the GetImage method retrieves the value of a runtime variable named GetImageProgress, and later uses this value as a function pointer. This variable is wiped out by the same module near the end of the function. By setting this UEFI variable from the OS to point into custom code, an attacker could achieve arbitrary code execution in the DXE phase, before several chipset locks are set.

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. UEFI implementations do not correctly protect and validate information contained in the 'MeSetup' UEFI variable. On some systems, this variable can be overwritten using operating system APIs. Exploitation of this vulnerability could potentially lead to denial of service for the platform.

An issue was discovered in SysPasswordDxe in Insyde InsydeH2O with kernel 5.0 through 5.5. System password information could optionally be stored in cleartext, which might lead to possible information disclosure. • https://www.insyde.com/security-pledge/SA-2023047 • CWE-312: Cleartext Storage of Sensitive Information •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. Due to insufficient input validation, an attacker can tamper with a runtime-accessible EFI variable to cause a dynamic BAR setting to overlap SMRAM. Se descubrió un problema en Insyde InsydeH2O con los kernels 5.0 a 5.5. Debido a una validación de entrada insuficiente, un atacante puede alterar una variable EFI accesible en tiempo de ejecución para provocar que una configuración de BAR dinámica se superponga a SMRAM. • https://www.insyde.com/security-pledge/SA-2023035 • CWE-20: Improper Input Validation •
