Summary

• 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.

  In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

  Cisco ASA, FMC, and FTD Software

  To help customers determine their exposure to vulnerabilities in Cisco ASA, FMC, and FTD Software, Cisco provides the Cisco Software Checker. This tool identifies any Cisco security advisories that impact a specific software release and the earliest release that fixes the vulnerabilities that are described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities that are described in all the advisories that the Software Checker identifies (“Combined First Fixed”).

  To use the tool, go to the Cisco Software Checker page and follow the instructions. Alternatively, use the following form to search for vulnerabilities that affect a specific software release. To use the form, follow these steps:

  1. Choose which advisories the tool will search-all advisories, only advisories with a Critical or High Security Impact Rating (SIR), or only this advisory.
  2. Choose the appropriate software.
  3. Choose the appropriate platform (for Cisco ASA and FTD Software only).
  4. Enter a release number-for example, 16.2.11 for Cisco ASA Software or 6.6.7 for Cisco FTD Software.
  5. Click Check.
