CVE-2022-0690Network attack vector

Reflected script execution via uncast route identifiers

Published Feb 19, 2022 · Updated Aug 2, 2024

Reflected XSS in Microweber before 1.2.11 allows remote attackers to execute script in a victim’s browser through crafted edit-route IDs. Four administrative edit controllers passed each route ID directly into view data, allowing nonnumeric markup to reach HTML; the patch coerces every ID to an integer. A victim must follow a crafted request, and script execution is confined to that victim’s browser context.
