Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 5073700. It is, therefore, affected by multiple vulnerabilities- An issue was discovered in Broadcom) LSI PCI-SV92EX Soft Modem Kernel Driver through 2.2.100.1 (aka AGRSM64.sys). There is Local Privilege Escalation to SYSTEM via a Stack Overflow in RTLCopyMemory (IOCTL 0x1b2150). An attacker can exploit this to elevate privileges from a medium-integrity process to SYSTEM.
This can also be used to bypass kernel-level protections such as AV or PPL, because exploit code runs with high-integrity privileges and can be used in coordinated BYOVD (bring your own vulnerable driver) ransomware campaigns. (CVE-2023-31096)
- A vulnerability exits in driver SmSerl64.sys in Motorola SM56 Modem WDM Driver v6.12.23.0, which allows low-privileged users to mapping physical memory 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. (CVE-2024-55414)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
