A vulnerability in the web management interface of the Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. The vulnerability is due to insufficient validation of user-supplied parameters for certain API endpoints. An attacker could exploit this vulnerability by sending crafted input to an affected API endpoint. A successful exploit could allow an attacker to execute arbitrary commands on the device with low system privileges. To successfully exploit this vulnerability, an attacker would need valid credentials for a user with Device permissions: by default, only Administrators, Security Approvers and Network Admins user accounts have these permissions.

Multiple vulnerabilities in the web management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. These vulnerabilities are due to insufficient validation of user-supplied parameters for certain API endpoints. An attacker could exploit these vulnerabilities by sending crafted input to an affected API endpoint. A successful exploit could allow an attacker to execute arbitrary commands on the device with low system privileges. To successfully exploit these vulnerabilities, an attacker would need valid credentials for a user who has Devices permissions. By default, only Administrator, Security Approver and Network Admin roles have these permissions. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is part of the November 2022 release of the Cisco ASA, FTD, and FMC Security Advisory Bundled publication. For a complete list of the advisories and links to them, see Cisco Event Response: November 2022 Semiannual Cisco ASA, FMC, and FTD Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-74838"].
