CISA has confirmed that ransomware operators are exploiting CVE-2025-14733, a critical remote-code-execution vulnerability affecting WatchGuard Firebox appliances. The bug can allow an unauthenticated attacker to execute code remotely under vulnerable configurations.

Improper authentication in the WatchGuard Agent allows an unauthenticated attacker with network access to cause the agent to execute arbitrary code with elevated privileges.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of WatchGuard FireWare OS. Authentication is not required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8. The following CVEs are assigned: CVE-2026-13086.

An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.

If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured.

A Cross-Site Request Forgery (CSRF) vulnerability in WatchGuard Dimension's database snapshot creation feature allows a remote attacker to trigger unauthorized snapshot creation by tricking an authenticated administrator into visiting a specially crafted web page.

An out-of-bounds read vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

A stack-based buffer overflow vulnerability in the WatchGuard Fireware OS iked process iallows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

An integer underflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

A buffer overflow vulnerability in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to cause a denial of service (DoS) condition or potentially execute arbitrary code by sending specially crafted network traffic.

A stack-based buffer overflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to execute arbitrary code by sending specially crafted network traffic.

A double-free vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

An out-of-bounds read vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

An integer underflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.

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.

Rejected reason: Rejecting as a duplicate of CVE-2026-78047

WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts. If the account lockout setting is enabled, brute-force attempts are blocked after a defined number of failed attempts, but this setting is not enabled by default.

A business logic flaw in WatchGuard Dimension allows an authenticated administrator to trigger multiple backend operations within a single logical flow by sending a specially crafted request.

A Stored Cross-Site Scripting (XSS) vulnerability in WatchGuard Dimension's Trusted CA certificate configuration allows an authenticated administrator to execute arbitrary JavaScript in another authenticated administrator's web browser by saving a carefully crafted certificate.

A server-side request forgery (SSRF) vulnerability WatchGuard Dimension FTP Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.

A blind server-side request forgery (SSRF) vulnerability WatchGuard Dimension Database Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.

WatchGuard Dimension contains an authenticated SQL injection vulnerability in the audit report feature which allows an authenticated user with report administration permissions gain arbitrary command execution as the Dimension WebUI process user by sending specially crafted requests.

A server-side request forgery (SSRF) vulnerability WatchGuard Dimension Email Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.

A Reflected Cross-Site Scripting (XSS) vulnerability in WatchGuard Dimension's report detail page allows an attacker to execute arbitrary JavaScript in a authenticated user's browser with a specially crafted URL.

WatchGuard Dimension contains an authenticated SQL injection vulnerability in the log viewer feature which allows an authenticated user with report administration permissions gain arbitrary command execution as the Dimension WebUI process user by sending specially crafted requests.

WatchGuard Dimension contains an authenticated SQL injection vulnerability in the scheduled report feature which allows an authenticated user with report administration permissions gain arbitrary command execution as the Dimension WebUI process user by sending specially crafted requests.

WatchGuard Dimension's Web UI exposes an administrator passphrase change action that lacks CSRF protection. An attacker who can induce an authenticated global administrator's browser to visit a crafted link or page can change that administrator's passphrase to an attacker-chosen value without the administrator's consent.

WatchGuard Dimension records unredacted session identifiers for logged-in users in its web UI diagnostic log. A low-privileged Dimension Administrator can retrieve this log and extract a Super Administrator's session token while that administrator is logged in, enabling account takeover.

WatchGuard Dimension provides a client-side lock/unlock UI control for management changes. The server-side configuration endpoint does not enforce this lock/unlock workflow state, allowing an authenticated administrator to submit configuration changes directly to the endpoint without first completing the UI unlock step. This allows an authenticated read-write administrator session to bypass the intended editing workflow and overwrite configuration changes being made by another concurrent administrator session.

A server-side request forgery (SSRF) vulnerability WatchGuard Dimension Remote Backup Connection Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.
