CVE-2021-32544Network attack vector

Authenticated DOM XSS via unfiltered search fields

Published May 11, 2021 · Updated Sep 17, 2024

DOM-based cross-site scripting in igt+ v3901 allows remote authenticated users to run malicious JavaScript through crafted search fields. The IGT search function fails to filter special characters in specific fields, allowing attacker-supplied script to execute in a user's browser when the search result is rendered. Exploitation requires a valid remote account and a victim who loads the affected search output; the documented impact is browser-side script execution with confidentiality and integrity effects, not service interruption.
