Detailsinfo

A vulnerability, which was classified as problematic, has been found in SUNIX Serial Driver x64 10.1.0.0. This issue affects an unknown part in the library snxpsamd.sys of the component IOCTL Handler. The manipulation with an unknown input leads to a signature verification vulnerability. Using CWE to declare the problem leads to CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability exits in driver snxpsamd.sys in SUNIX Serial Driver x64 - 10.1.0.0, which allows low-privileged users to read and write arbitary i/o port via specially crafted IOCTL requests . This can be exploited for privilege escalation, code execution under high privileges, and information disclosure. These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious code.

The identification of this vulnerability is CVE-2024-55412 since 12/06/2024. The exploitation is known to be difficult. Technical details are known, but no exploit is available.
