CVE-2024-6592
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn incorrect authorization vulnerability in the protocol communication between the WatchGuard Authentication Gateway (aka Single Sign-On Agent) on Windows and the WatchGuard Single Sign-On Client on Windows and MacOS allows an attacker with network access to forge communications to affected components. In the event an attacker has already gained network access, they could exploit this vulnerability to retrieve authenticated usernames and group memberships from the Single Sign-On Agent or send arbitrary account and group information to the Single Sign-On Agent for their host. This vulnerability cannot be used by an attacker to gain access to user credentials.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn incorrect authorization vulnerability exists in the protocol communication between the WatchGuard Authentication Gateway (SSO Agent) and the WatchGuard Single Sign-On Client on Windows and MacOS. This allows an attacker to bypass authentication by exploiting the flawed authorization checks in the SSO communication protocol.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify WatchGuard Authentication Gateway versionLocate the Authentication Gateway SSO Agent installation and retrieve its version number, typically found in program information, installed software list, or via the product's management interfaceAffected if The version is 12.10.2 or lower
-
Identify WatchGuard SSO Client version on WindowsLocate the WatchGuard Single Sign-On Client installation on Windows systems and retrieve its version number from installed programs or the client application itselfAffected if The version is 12.7 or lower on Windows
-
Identify WatchGuard SSO Client version on MacOSLocate the WatchGuard Single Sign-On Client installation on MacOS systems and retrieve its version number from Applications or system profilerAffected if The version is 12.5.4 or lower on MacOS
-
Confirm SSO communication is activeVerify that the WatchGuard SSO Agent and SSO Client are configured and actively communicating on the network, as the vulnerability only applies when the protocol communication is in useAffected if SSO communication is enabled and the component versions are within the affected ranges
You are affected if WatchGuard Authentication Gateway is at version 12.10.2 or lower, or Windows SSO Client is at 12.7 or lower, or MacOS SSO Client is at 12.5.4 or lower, and the SSO communication between these components is active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the WatchGuard Authentication Gateway to a version beyond 12.10.2, Windows SSO Client beyond 12.7, and MacOS SSO Client beyond 12.5.4 to remediate the authorization bypass vulnerability.
