CVE-2023-48659Network attack vector

Script execution via unfiltered Galaxy parameters

Published Nov 17, 2023 · Updated Aug 2, 2024

Reflected XSS in MISP before 2.4.176 allows remote attackers to execute script in a user's browser through crafted Galaxy parameters. AppController.php's _harvestParameters method merged arbitrary request-body keys into parsed data instead of limiting input to each action's paramArray. A targeted user must open the crafted Galaxy request; injected script runs in that user's MISP origin and can act with the user's session.
