CVE-2024-47190 is a Server-Side Request Forgery (SSRF) vulnerability identified in Northern.tech Hosted Mender, a platform used for managing and updating embedded Linux devices. The vulnerability exists in versions prior to 2024.07.11 and allows an attacker with authenticated high-level privileges to coerce the server into making arbitrary HTTP requests. SSRF vulnerabilities typically arise when user-supplied URLs or network requests are not properly validated, enabling attackers to interact with internal systems or external endpoints on behalf of the server. In this case, the attacker can potentially access internal network resources or services that are otherwise inaccessible externally, leading to limited confidentiality breaches. The CVSS 3.1 base score is 2.7, indicating low severity due to the requirement for high privileges (PR:H), no user interaction (UI:N), and limited impact confined to confidentiality (C:L) without affecting integrity or availability. No public exploits have been reported, and no patch links were provided, but the fix is included in Northern.tech Hosted Mender version 2024.07.11 and later. The vulnerability is classified under CWE-918 (Server-Side Request Forgery).

The primary impact of CVE-2024-47190 is the potential unauthorized disclosure of sensitive information accessible via internal network resources. An attacker exploiting this SSRF vulnerability could perform reconnaissance on internal services, access metadata endpoints, or retrieve sensitive data from internal APIs or databases that are not exposed externally. However, since the vulnerability requires authenticated access with high privileges, the risk is limited to insiders or compromised accounts with elevated permissions. There is no direct impact on data integrity or system availability. Organizations relying on Northern.tech Hosted Mender for managing embedded devices could face increased risk of internal network exposure or data leakage if this vulnerability is exploited in conjunction with other weaknesses. The absence of known exploits in the wild reduces immediate threat urgency but does not eliminate the need for remediation.

To mitigate CVE-2024-47190, organizations should upgrade Northern.tech Hosted Mender to version 2024.07.11 or later where the SSRF vulnerability is addressed. Additionally, implement strict access controls and monitoring for accounts with high privileges to reduce the risk of credential compromise. Network segmentation should be enforced to limit the server's ability to reach sensitive internal resources unnecessarily. Employ web application firewalls (WAFs) or network-level filtering to detect and block suspicious outbound requests originating from the Mender server. Conduct regular audits of internal services to ensure they do not expose sensitive data to SSRF attacks. Finally, review and harden input validation and URL handling mechanisms in custom integrations or extensions to prevent SSRF exploitation.
