Stored XSS via insufficient input validation
Published Nov 1, 2023 · Updated Aug 2, 2024
Stored XSS in Cisco Firepower Management Center allows remote attackers to execute scripts through crafted web-interface fields. The management interface stores user-supplied field values without sufficient validation and later renders the crafted content in another user's browser; Cisco does not identify the specific fields or handlers. No authentication is required to plant the content, but a user must view the affected interface; execution is confined to that browser context and can expose browser-held data or temporarily impair parts of the dashboard.
