CVE-2023-50378Network attack vector

Session hijacking via stored cross-site scripting

Published Mar 1, 2024 · Updated Nov 7, 2024

Stored XSS in Apache Ambari 2.7.0 through 2.7.7 allows remote attackers to execute browser code through persistent crafted input. Apache identifies inadequate input validation and constraint enforcement but does not disclose the affected fields, endpoints, or code path. Exploitation requires a user to view the stored payload, enabling data access, session hijacking, unauthorized actions, or malicious-payload delivery in that user's browser.
