0
Critical
Published: 09/25/2024 (09/25/2024, 11:16:01 UTC)
Source: CVE Database V5
Vendor/Project: WatchGuard
Product: SSO Client

Description

An 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 Analysis

This vulnerability (CVE-2024-6592) involves incorrect authorization in the protocol communication between the WatchGuard Authentication Gateway (Single Sign-On Agent) on Windows and the WatchGuard Single Sign-On Client on Windows and MacOS. An attacker with network access can forge communications to affected components, enabling them to retrieve authenticated usernames and group memberships or send arbitrary account and group information to the Single Sign-On Agent on their host. The vulnerability does not permit access to user credentials. It is identified as CWE-306 (Incorrect Authorization) and has a CVSS v4.0 score of 9.3, indicating critical severity.

Potential Impact

An attacker with network access can exploit this vulnerability to impersonate or manipulate Single Sign-On communications, allowing retrieval of authenticated usernames and group memberships or injection of arbitrary account and group information. However, the vulnerability does not enable attackers to obtain user credentials, limiting the scope of direct credential compromise.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor WatchGuard advisories for updates. Network access is required for exploitation, so restricting network access to the Single Sign-On components may reduce exposure.
