CVE-2024-29011 is a vulnerability classified under CWE-259, indicating the use of a hard-coded password within the SonicWall Global Management System (GMS), specifically in the ECM endpoint. This hard-coded credential allows attackers to bypass authentication controls remotely without requiring any privileges or user interaction. The affected versions include GMS 9.3.4 and all earlier releases. The vulnerability has a CVSS v3.1 base score of 7.5, reflecting its high severity due to network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact is primarily on confidentiality, as unauthorized access to the management system could expose sensitive configuration data and network topology information, but it does not directly compromise integrity or availability. SonicWall GMS is widely used for centralized management of SonicWall firewalls and other security appliances, making this vulnerability a significant risk for organizations relying on this platform for network security administration. Although no exploits have been reported in the wild yet, the presence of a hard-coded password is a critical security flaw that could be leveraged by attackers to gain persistent unauthorized access. The lack of an available patch at the time of reporting necessitates immediate risk mitigation through compensating controls.

For European organizations, the exploitation of this vulnerability could lead to unauthorized access to SonicWall GMS, exposing sensitive network management data and potentially enabling attackers to gather intelligence for further attacks. This breach of confidentiality could undermine the security posture of enterprises, government agencies, and critical infrastructure operators. Since GMS controls multiple security devices, unauthorized access might allow attackers to manipulate configurations indirectly or prepare for subsequent attacks, although direct integrity or availability impacts are not indicated. The risk is heightened in sectors with stringent data protection requirements such as finance, healthcare, and public administration. Additionally, organizations that have not updated their SonicWall GMS installations are particularly vulnerable. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially given the ease of exploitation and the critical nature of the affected systems.

1. Immediately inventory all SonicWall GMS deployments and identify versions 9.3.4 and earlier. 2. Monitor SonicWall official channels for patches or security advisories addressing CVE-2024-29011 and apply updates promptly once available. 3. Until patches are released, restrict network access to the GMS ECM endpoint using network segmentation and firewall rules to limit exposure to trusted administrators only. 4. Implement strict access controls and multi-factor authentication on management systems to reduce risk if the hard-coded password is exploited. 5. Conduct regular audits and monitoring of GMS logs for unusual authentication attempts or access patterns. 6. Consider deploying intrusion detection/prevention systems to alert on suspicious activity targeting the GMS. 7. Educate IT and security teams about the vulnerability and ensure incident response plans include scenarios involving management system compromise. 8. Evaluate alternative management solutions or upgrade paths if SonicWall support for affected versions is limited.
