Cisco Secure Firewall Management Center Software Vulnerabilities

Cisco fixed multiple Secure Firewall Management Center flaws enabling remote attackers to gain root access, download files, inject SQL, or cause DoS.

Multiple vulnerabilities in Cisco Secure Firewall Management Center (FMC) software could allow a remote attacker to gain root access, download sensitive files, perform SQL injection attacks, or cause a denial of service condition. Cisco released software updates addressing the issues. No workarounds are available, and the advisory is part of a grouped release of Cisco advisories.

Cisco Secure Firewall Threat Defense Software TLS 1.3 Denial of Service Vulnerability

A TLS 1.3 buffer management flaw in Cisco Secure Firewall Threat Defense lets remote attackers crash the LINA process and reload devices.

A vulnerability in the TLS 1.3 implementation of Cisco Secure Firewall Threat Defense (FTD) software allows an unauthenticated remote attacker to cause a denial of service via crafted TLS 1.3 packets sent to a TLS 1.3-enabled listening socket. Improper buffer management causes the LINA process to crash, forcing a device reload that can occur before or after connection authentication. Cisco has released software updates to address the flaw.

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.

AWS makes it easier to spot firewall rules that have gone quiet

AWS Network Firewall added rule hit counts for stateful rules, letting teams identify unused rules and validate control effectiveness at no added cost.

AWS Network Firewall's rule hit count capability gives security teams visibility into which stateful firewall rules are matching traffic, helping identify unused or redundant rules and validate controls for compliance frameworks like PCI DSS 4.0 and DORA. The feature covers stateful rules in custom and managed rule groups, is enabled by default at no additional Network Firewall cost, and is available in all supported Regions except UAE and Bahrain. Data is surfaced in the Network Firewall dashboard's Top Rule Hits view and can be queried via CloudWatch Logs Insights or Amazon Athena.

Cisco Industrial Ethernet 1000 Series Switches Denial of Service Vulnerability

Cisco released a fix for a management-plane flooding DoS in IE-1000 switches that can make the device manager, SSH, or API inaccessible.

Insufficient protection against management plane flooding in Cisco Industrial Ethernet 1000 Series Switches allows an unauthenticated remote attacker to send high-rate ICMP, SSH, or HTTP traffic, raising CPU usage and causing a denial-of-service condition on the device manager web GUI, SSH, or API. Data traffic through the device is not affected. Cisco has released software updates to address the issue.
