The vulnerability of the SysPasswordDxe component in the InsydeH2O UEFI firmware creation framework allows a hacker to access confidential information.
The vulnerability of the SysPasswordDxe component in the InsydeH2O UEFI firmware creation framework is related to the unencrypted storage of credentials. Exploiting this vulnerability could allow a malicious actor, operating remotely, to gain access to confidential information...
Siemens InsydeH2O Out-of-bounds Write (CVE-2022-35895)
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The FwBlockSericceSmm driver does not properly validate input parameters for a software SMI routine, leading to memory corruption of arbitrary addresses including SMRAM, and possible arbitrary code execution. Insyde BIOS is...
Siemens InsydeH2O Improper Restriction of Operations within the Bounds of a Memory Buffer (CVE-2021-41839)
An issue was discovered in NvmExpressDxe in the kernel 5.0 through 5.5 in Insyde InsydeH2O. Because of an Untrusted Pointer Dereference that causes SMM memory corruption, an attacker may be able to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges...
Siemens InsydeH2O Time-of-check Time-of-use Race Condition (CVE-2022-32478)
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the IdeBusDxe shared buffer used by SMM and non- SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated using IOMMU...
Siemens InsydeH2O Inclusion of Functionality from Untrusted Control Sphere (CVE-2021-41841)
An issue was discovered in AhciBusDxe in the kernel 5.0 through 5.5 in Insyde InsydeH2O. There is an SMM callout that allows an attacker to access the System Management Mode and execute arbitrary code. This occurs because of Inclusion of Functionality from an Untrusted Control Sphere. Insyde BIOS...
Siemens InsydeH2O Cleartext Storage of Sensitive Information (CVE-2023-31041)
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. Insyde BIOS is typically used in RUGGEDCOM APE products and some SIMATIC devices...
Siemens InsydeH2O Out-of-bounds Write (CVE-2023-22615)
An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI subfunction execution may corrupt SMRAM. An attacker can pass an address in the RCX save state register that overlaps SMRAM, thereby coercing an IHISI subfunction handler to overwrite private SMRAM. Insyde...
