CVE-2020-1090
HighCVSS 7.8Exploitation Probability (EPSS)
Elevated risk52th percentile - higher than 52% of all known CVEs
Summary
Elevation of privilege vulnerability in Windows Runtime due to improper handling of objects in memory. An attacker could run arbitrary code in an elevated context.
Risk Assessment
Risk of gaining administrative control over the system, potentially leading to full system compromise.
Recommendation
Install the security update provided by Microsoft that corrects the memory object handling.

Original NVD description (English source)
An elevation of privilege vulnerability exists when the Windows Runtime improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in an elevated context. An attacker could exploit this vulnerability by running a specially crafted application on the victim system. The update addresses the vulnerability by correcting the way the Windows Runtime handles objects in memory.
