3DescriptionCVE.org
A vulnerability was determined in ieungSoft Ultra RAMDisk Pro 1.82. This issue affects some unknown processing in the library URDSCSI.sys of the component Kernel Driver. This manipulation causes improper privilege management. The attack needs to be launched locally. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Local privilege escalation in ieungSoft Ultra RAMDisk Pro 1.82 allows a low-privileged local user to gain SYSTEM or kernel-level control via improper privilege management in the URDSCSI.sys kernel driver (CWE-266). The vendor did not respond to coordinated disclosure, leaving no official patch; a public proof-of-concept exploit exists, confirmed by the CVSS 4.0 E:P metric and a detailed write-up. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a Windows system with Ultra RAMDisk Pro 1.82 installed and the URDSCSI.sys driver service actively loaded and running. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base vector (AV:L/AC:L/AT:N/PR:L/UI:N) with VC:H/VI:H/VA:H/SC:H/SI:H/SA:H reflects a straightforward, low-complexity local privilege escalation with full impact on both the vulnerable system and subsequent systems in scope - consistent with a kernel-level compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the vendor did not respond to coordinated disclosure, and no fix version has been published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running ieungSoft Ultra RAMDisk Pro 1.82 and disable or uninstall the software if business operations permit; if retention is unavoidable, disable the URDSCSI.sys kernel driver immediately via Windows Boot Configuration Data settings. …
