FKIE_CVE-2026-20316
Vulnerability from fkie_nvd - Published: 2026-07-29 17:16 - Updated: 2026-08-01 05:16
Severity
Summary
A vulnerability in the web interface of Cisco Secure Firewall Management Center (FMC) Software could allow an unauthenticated, remote attacker to log in to an affected device using a low-privileged account to access sensitive data within the impacted systems.
This vulnerability is due to the presence of static user credentials for a low-privileged account. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user.
Note: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced.
Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates. The reason is that this vulnerability can be used with other Cisco Secure FMC Software vulnerabilities to elevate privileges.
