CVE-2020-1195
LowCVSS 3.1Exploitation Probability (EPSS)
High risk84th percentile - higher than 84% of all known CVEs
Summary
Elevation of privilege vulnerability in Microsoft Edge (Chromium-based) due to improper input validation in the Feedback extension. An attacker could write files to arbitrary locations and gain elevated privileges. The vulnerability alone does not allow arbitrary code execution but can be chained with other vulnerabilities.
Risk Assessment
Risk of privilege escalation in the browser, potentially allowing file writes and further attacks.
Recommendation
Install the Microsoft Edge security update that modifies how the Feedback extension validates files.
Original NVD description (English source)
An elevation of privilege vulnerability exists in Microsoft Edge (Chromium-based) when the Feedback extension improperly validates input. An attacker who successfully exploited this vulnerability could write files to arbitrary locations and gain elevated privileges. The vulnerability by itself does not allow arbitrary code to run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (for example a remote code execution vulnerability and another elevation of privilege vulnerability) to take advantage of the elevated privileges when running. The security update addresses the vulnerability by modifying how Microsoft Edge (Chromium-based) Feedback extension validates files.
