CVE-2022-42972
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA CWE-732: Incorrect Permission Assignment for Critical Resource vulnerability exists that could cause local privilege escalation when a local attacker modifies the webroot directory. Affected Products: APC Easy UPS Online Monitoring Software (Windows 7, 10, 11 & Windows Server 2016, 2019, 2022 - Versions prior to V2.5-GA), APC Easy UPS Online Monitoring Software (Windows 11, Windows Server 2019, 2022 - Versions prior to V2.5-GA-01-22261), Schneider Electric Easy UPS Online Monitoring Software (Windows 7, 10, 11 & Windows Server 2016, 2019, 2022 - Versions prior to V2.5-GS), Schneider Electric Easy UPS Online Monitoring Software (Windows 11, Windows Server 2019, 2022 - Versions prior to V2.5-GS-01-22261)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA sensitive file, directory, or resource is created with permissions more open than it needs, so unintended users can read or modify it. Attackers look for exactly these loose defaults. Remediation is assigning the minimum permissions required and verifying them at install time and at runtime.
