Technical details

This SQL injection vulnerability in Cisco Secure FMC Software's web-based management interface stems from insufficient validation of user-supplied input in database queries. The vulnerability is network-reachable and requires authentication with specific elevated roles (Security Approver, Access Admin, or Network Admin). An attacker can exploit this by sending a crafted HTTP request to the affected web interface, allowing them to obtain arbitrary data from the database, retrieve session credentials of authenticated administrators, and execute administrative actions on the affected device. The CVSS v3.1 base score is 8.8 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating a high-severity vulnerability with network attack vector and high privilege requirements.
