CVE-2021-34751


A vulnerability 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 an affected device. This vulnerability exists because of improper encryption of sensitive information stored within the GUI configuration manager. An attacker could exploit this vulnerability 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 this vulnerability. There are no workarounds that address this vulnerability.[[Publication_URL{Layout()}]]This advisory is part of the October 2021 release of the Cisco ASA, FTD, and FMC Security Advisory Bundled publication.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
