CVE-2020-0728
Status: ModifiedMedium (5.5)—💥 PoC
An information vulnerability exists when Windows Modules Installer Service improperly discloses file information, aka 'Windows Modules Installer Service Information Disclosure Vulnerability'.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
- Base score: 5.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 3.73%
- Percentile among all scored CVEs: 90
- Score date: 10/17/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
