CVE-2021-33834 1 Insyde 2 H2offt, Iscflashx64.sys 2024-11-21 7.1 High
An issue was discovered in iscflashx64.sys 3.9.3.0 in Insyde H2OFFT 6.20.00. When handling IOCTL 0x22229a, the input used to allocate a buffer and copy memory is mishandled. This could cause memory corruption or a system crash.
CVE-2021-33627 2 Insyde, Siemens 29 Insydeh2o, Simatic Field Pg M5, Simatic Field Pg M5 Firmware and 26 more 2024-11-21 8.2 High
An issue was discovered in Insyde InsydeH2O Kernel 5.0 before 05.09.11, 5.1 before 05.17.11, 5.2 before 05.27.11, 5.3 before 05.36.11, 5.4 before 05.44.11, and 5.5 before 05.52.11 affecting FwBlockServiceSmm. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses.
CVE-2021-33626 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Apr1808, Ruggedcom Apr1808 Firmware and 30 more 2024-11-21 7.8 High
A vulnerability exists in SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer(QWORD values for CommBuffer). This can be used by an attacker to corrupt data in SMRAM memory and even lead to arbitrary code execution.
CVE-2021-33625 3 Insyde, Netapp, Siemens 34 Insydeh2o, Fas\/aff Bios, Ruggedcom Ape1808 and 31 more 2024-11-21 7.5 High
An issue was discovered in Kernel 5.x in Insyde InsydeH2O, affecting HddPassword. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses.
CVE-2020-5956 1 Insyde 1 Insydeh2o 2024-11-21 7.5 High
An issue was discovered in SdLegacySmm in Insyde InsydeH2O with kernel 5.1 before 05.15.11, 5.2 before 05.25.11, 5.3 before 05.34.11, and 5.4 before 05.42.11. The software SMI handler allows untrusted external input because it does not verify CommBuffer.
CVE-2020-5955 2 Insyde, Intel 21 Insydeh2o Uefi Bios, Cannon Lake, Coffee Lake and 18 more 2024-11-21 9.8 Critical
An issue was discovered in Int15MicrocodeSmm in Insyde InsydeH2O before 2021-10-14 on Intel client chipsets. A caller may be able to escalate privileges.
CVE-2020-5953 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Ape1808, Ruggedcom Ape1808 Firmware and 30 more 2024-11-21 7.5 High
A vulnerability exists in System Management Interrupt (SWSMI) handler of InsydeH2O UEFI Firmware code located in SWSMI handler that dereferences gRT (EFI_RUNTIME_SERVICES) pointer to call a GetVariable service, which is located outside of SMRAM. This can result in code execution in SMM (escalating privilege from ring 0 to ring -2).
CVE-2020-27339 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Apr1808, Ruggedcom Apr1808 Firmware and 30 more 2024-11-21 6.7 Medium
In the kernel in Insyde InsydeH2O 5.x, certain SMM drivers did not correctly validate the CommBuffer and CommBufferSize parameters, allowing callers to corrupt either the firmware or the OS memory. The fixed versions for this issue in the AhciBusDxe, IdeBusDxe, NvmExpressDxe, SdHostDriverDxe, and SdMmcDeviceDxe drivers are 05.16.25, 05.26.25, 05.35.25, 05.43.25, and 05.51.25 (for Kernel 5.1 through 5.5).
CVE-2019-12532 1 Insyde 6 H2oelv, H2offt, H2ooae and 3 more 2024-11-21 7.8 High
Improper access control in the Insyde software tools may allow an authenticated user to potentially enable escalation of privilege, or information disclosure via local access. This is a software vulnerability, not a firmware issue. Affected tools include: H2OFFT version 3.02~5.28, 100.00.00.00~100.00.08.23 and 200.00.00.01~200.00.00.05, H2OOAE before version 200.00.00.02, H2OSDE before version 200.00.00.07, H2OUVE before version 200.00.02.02, H2OPCM before version 100.00.06.00, H2OELV before version 100.00.02.08.
