Firepower 4100 vulnerabilitiesRanked by how likely they are to be used.
Firepower 4100 is made by Cisco. We track 13 published vulnerabilities listed under that exact name, across 0 versions. None of them is on the list of flaws known to be exploited today. Cisco lists newer releases under their own names, such as Firepower 4100 Next-Generation Firewall Firmware, so check those pages too.
We keep watching the known-exploited list.
Is Firepower 4100 listed under other names? Yes.
Cisco also lists Firepower 4100 under more specific names, such as Firepower 4100 Next-Generation Firewall Firmware. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
Which Firepower 4100 vulnerabilities are being exploited?
This is the list that matters most: flaws criminals are using now.
None of Firepower 4100's published vulnerabilities is on the list of flaws known to be exploited today. We keep watching that list.
Which Firepower 4100 flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.

1 new flaw affects software Acme tracks
A vulnerability in the handling of RSA keys on devices running Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to retrieve an RSA private key. This vulnerability is due to a logic error when the RSA key is stored in memory on a hardware platform that performs hardware-based cryptography. An attacker could exploit this vulnerability by using a Lenstra side-channel attack against the targeted device. A successful exploit could allow the attacker to retrieve the RSA private key. The following conditions may be observed on an affected device: This vulnerability will apply to approximately 5 percent of the RSA keys on a device that is running a vulnerable release of Cisco ASA Software or Cisco FTD Software; not all RSA keys are expected to be affected due to mathematical calculations applied to the RSA key. The RSA key could be valid but have specific characteristics that make it vulnerable to the potential leak of the RSA private key. If an attacker obtains the RSA private key, they could use the key to impersonate a device that is running Cisco ASA Software or Cisco FTD Software or to decrypt the device traffic. See the Indicators of Compromise section for more information on the detection of this type of RSA key. The RSA key could be malformed and invalid. A malformed RSA key is not functional, and a TLS client connection to a device that is running Cisco ASA Software or Cisco FTD Software that uses the malformed RSA key will result in a TLS signature failure, which means a vulnerable software release created an invalid RSA signature that failed verification. If an attacker obtains the RSA private key, they could use the key to impersonate a device that is running Cisco ASA Software or Cisco FTD Software or to decrypt the device traffic.
