Cisco Secure Firewall Management Center Software Authentication Bypass Vulnerability

Cisco warns of a critical authentication bypass in Secure Firewall Management Center that lets unauthenticated attackers execute scripts and obtain root access.

A vulnerability in the web interface of Cisco Secure Firewall Management Center (FMC) Software allows an unauthenticated, remote attacker to bypass authentication and execute script files on an affected device to obtain root access to the underlying operating system. The flaw stems from an improper system process created at boot time and is triggered via crafted HTTP requests. If the FMC management interface does not have public internet access, the attack surface is limited.

cPanel ConfigServer Security & Firewall Vulnerability Allows Remote Attacker to Execute Arbitrary Commands

CSF 14.00–16.29 (CVE-2026-65638) lets unauthenticated attackers execute arbitrary commands via the MESSENGER service on cPanel/WHM servers; version 16.30 fixes it.

CVE-2026-65638 affects ConfigServer Security & Firewall (CSF) versions 14.00 through 16.29 and allows unauthenticated remote attackers to execute arbitrary commands through the MESSENGER service, running under the unprivileged CSF service account rather than root. Exploitation requires the non-default MESSENGER service to be enabled and a reCAPTCHA secret configured, reducing exposure for standard deployments. CSF 16.30 and later fix the flaw; administrators who cannot update immediately can set MESSENGER = 0 in /etc/csf/csf.conf as a temporary mitigation.

Cisco Secure Firewall Management Center Software Static Credential Vulnerability

Cisco warns of static low-privileged credentials in Secure Firewall Management Center's web interface, letting unauthenticated remote attackers log in and access sensitive data.

Cisco disclosed a vulnerability in the web interface of Secure Firewall Management Center (FMC) Software caused by the presence of static credentials for a low-privileged account. An unauthenticated remote attacker could log in to an affected device using the static account and access sensitive data within impacted systems. The attack surface is reduced when the FMC management interface does not have public internet access.

Cisco confirms CVE-2026-20079 Secure FMC flaw exploited in attacks

Cisco confirmed active exploitation of CVE-2026-20079, a CVSS 10.0 authentication bypass enabling unauthenticated root command execution in Secure FMC; CISA added it to KEV.

Cisco confirmed in August 2026 that CVE-2026-20079 (CVSS 10.0), an unauthenticated authentication bypass in Secure Firewall Management Center, is being actively exploited, allowing remote attackers to execute scripts and commands as root via crafted HTTP requests to the web interface. CISA added the flaw to its Known Exploited Vulnerabilities catalog, ordering federal civilian agencies to patch by September 12, 2026. Shared IOCs, identical hot fixes, and a July 23 log entry suggest CVE-2026-20079 was used alongside the separately exploited static-credential flaw CVE-2026-20316 in the same attacks. Cisco released patches and cloud fixes, warns hot fixes do not remediate already-compromised devices, and says there are no workarounds.
