đź”’ CVE-2025-21391 Mitigation Script
Mitigate the Windows Storage Elevation of Privilege Vulnerability (CVE-2025-21391) without patching, temporarily reducing the risk of exploitation.
🔍 How it works:
This script disables the Windows Storage service (storSvc) to prevent exploitation of the vulnerability. While this doesn’t patch the issue, it reduces the likelihood of attack and provides temporary protection until a patch is applied.
⚠️ Why it matters:
CVE-2025-21391 can lead to file deletion and service disruptions. While this script disables the vulnerable service as a temporary workaround, it is crucial to apply official security patches as soon as possible to fully mitigate the vulnerability and secure your system.
