CVE-2026-20316: Cisco Secure Firewall Management Center Use of Hard-coded Password Vulnerability

CISA Known Exploited Vulnerabilities | July 29, 2026 | Known Exploited | Cisco Secure Firewall Management Center (FMC)

Cisco Secure Firewall Management Center (FMC) formerly known as Firepower Management Center contains a use of hard-coded password vulnerability that 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.

Why it matters: Cisco Secure Firewall Management Center (FMC) must be evaluated at the edge, management plane, firmware level, and independent logging path.

What to verify: Confirm the affected version and reachable component, preserve useful telemetry, apply the publisher guidance, and record the evidence used to close the item.

CISA remediation date: 2026-08-01. Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance…

Operational focus: Identify exposed management interfaces and confirm the exact firmware or software version.

CVE-2025-68686: Fortinet FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability

CISA Known Exploited Vulnerabilities | July 27, 2026 | Known Exploited | Fortinet FortiOS

Fortinet FortiOS contains an exposure of sensitive information to an unauthorized actor vulnerability. This may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.

Why it matters: Fortinet FortiOS commonly protects an internet edge or management boundary. Exposure there can affect remote access, traffic inspection, credentials, and the trust placed in downstream systems.

What to verify: Check the running firmware and model, restrict management access, compare configuration changes and new accounts, preserve independent logs, and rotate credentials if compromise cannot be excluded.

CISA remediation date: 2026-08-10. Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance…

Operational focus: Restrict administrative access to trusted networks and rotate credentials after suspected compromise.

CVE-2026-41939: Care Everywhere Gateway 14.3.10 contains a hard-coded credentials vulnerability in the bundled…

NIST National Vulnerability Database | July 29, 2026 | CRITICAL | CVSS 9.8

Care Everywhere Gateway 14.3.10 contains a hard-coded credentials vulnerability in the bundled WildFly 8.2.0.Final management interface that allows unauthenticated remote attackers to gain administrative access by using default credentials identical across all installations. Attackers can authenticate to the exposed WildFly management console on port 20990 and deploy a malicious Web Application Archive file through the Deployments interface to…

Why it matters: CVE-2026-41939 is likely connected to identity, collaboration, or privileged Windows workloads, where one exposed role can widen impact beyond a single endpoint.

What to verify: Map supported builds and server roles, prioritize public and identity systems, confirm the installed update plus restart state, and review authentication and EDR telemetry for abnormal activity.
