Symptom
Multiple vulnerabilities in the administrative web-based GUI configuration manager of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to access sensitive configuration information. The attacker would require low privilege credentials on the device.
These vulnerabilities are due to a lack of proper encryption of sensitive information stored within the GUI configuration manager. An attacker could exploit these vulnerabilities by logging into the GUI of Cisco FMC Software and navigating to certain sensitive configurations. A successful exploit could allow the attacker to view sensitive configuration parameters in clear text.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
