Summary
A buffer overflow in WatchGuard Fireware OS may allow an authenticated remote attacker with privileged management access to execute arbitrary code with system privileges on the firewall. This issue affects Fireware OS from 11.9.6 through 12.10.3.
Risk Assessment
An attacker with management privileges can gain full control of the firewall, potentially leading to network security compromise.
Recommendation
Upgrade WatchGuard Fireware OS to a version later than 12.10.3, which includes the fix.
Other vulnerabilities in WatchGuard Fireware OS
See all- CVE-2026-93866Critical
An integer overflow vulnerability exists in the WebSocket connection handling used by WatchGuard Fireware OS's Access Portal. A remote, unauthenticated attacker can write beyond the bounds of a heap buffer by sending a specially crafted request while the Access Portal feature is enabled.
- CVE-2026-93865Critical
A missing authentication vulnerability exists in the Fireware OS FireCluster synchronization daemon. A remote, unauthenticated attacker can invoke privileged system-level administrative actions by sending a specially crafted request to the FireCluster management IP when the clustering feature is enabled.
- CVE-2026-93857Critical
A stack-based buffer overflow vulnerability exists in Fireware OS's SIP proxy. A remote, unauthenticated attacker can execute arbitrary code by sending a specially crafted request through a policy that uses the SIP proxy.
- CVE-2026-90465Critical
A missing authentication vulnerability exists in FireCluster Sync processing. An attacker positioned on the cluster interconnect, such as a compromised cluster peer or an on-path network attacker, can invoke privileged firewall management actions as root by sending a specially crafted request.
- CVE-2026-112710Critical
A heap-based buffer overflow vulnerability exists in the Fireware OS authentication service. An attacker who controls or intercepts traffic to the configured Active Directory server can create a denial of service condition and potentially execute arbitrary code by returning a specially crafted response.
- CVE-2026-112709Critical
A heap-based buffer overflow vulnerability exists in the Fireware OS authentication service. An attacker who controls or intercepts traffic to the configured Active Directory server can create a denial of service condition and potentially execute arbitrary code by returning a specially crafted response.
- CVE-2026-103594Critical
A stack-based buffer overflow vulnerability exists in Fireware OS's WireGuard configuration processing. A remote attacker with man-in-the-middle TLS-decrypted access between the Firebox and WatchGuard Cloud can create a denial of service condition and potentially execute arbitrary code by tampering with a FireCloud Gateway configuration payload.
- CVE-2026-86131Critical
A code injection vulnerability in WatchGuard Fireware OS's BOVPN Over TLS client configuration handling allows an attacker who controls the remote VPN server to execute arbitrary commands as root on the connecting Firebox.
- CVE-2026-19318Critical
A stack-based buffer overflow in the iked process of WatchGuard Fireware OS allows a remote unauthenticated attacker to execute arbitrary code by sending specially crafted network traffic.
- CVE-2026-19315Critical
A type confusion vulnerability in the iked process of WatchGuard Fireware OS allows a remote unauthenticated attacker to execute arbitrary code by sending specially crafted network traffic.
