Samsung MagicINFO 9 Server Path Traversal (CVE-2024-7399)

Historical catalog analysis: CISA added this entry on April 24, 2026. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2024-7399 is a path traversal vulnerability (CWE-22) and unrestricted upload of file with dangerous functionality (CWE-434) affecting Samsung MagicINFO 9 Server. The flaw allows an attacker to write arbitrary files to the system with system-level authority.

Exposure and applicability

This vulnerability applies specifically to environments deploying the Samsung MagicINFO 9 Server. Because this software often manages digital signage across a corporate or campus network, exposure is highest where the server is accessible from untrusted network segments. The inclusion of this CVE in CISA’s Known Exploited Vulnerabilities (KEV) catalog indicates that the vulnerability has been observed in active exploitation, increasing the urgency for infrastructure owners to identify affected assets.

Remediation priorities

Based on the reported risk and its status as a known exploited vulnerability, we analyze the following prioritization strategy:

1. Immediate Asset Identification: Infrastructure teams should prioritize identifying all instances of MagicINFO 9 Server across the environment. Given the system-level authority associated with the file write, these assets should be treated as high-priority targets for remediation.
2. Vendor Mitigation Deployment: The primary corrective action is to apply mitigations provided by Samsung. Organizations should verify the current version against vendor security updates to determine if a patch or configuration change is available.
3. Network Isolation: For systems where immediate patching is not feasible, we suggest restricting network access to the MagicINFO 9 Server management interface to known, authorized administrative IPs to reduce the likelihood of external exploitation.
4. Cloud Service Review: Organizations utilizing this product via cloud services should review their implementation against BOD 22-01 guidance to ensure shared responsibility for vulnerability management is being met by the provider.

How to validate remediation

Verification must go beyond a simple version check, as a deployed update does not always guarantee that the vulnerability is neutralized in a specific environment. We recommend the following validation approach:

• Configuration Audit: Verify that the mitigations specified in the vendor’s security updates have been applied and are active.
• File System Integrity Check: In environments where exploitation is suspected, defenders should inspect system directories for unauthorized files created with system authority.
• Access Control Validation: Confirm through network telemetry or firewall logs that access to the server is restricted to authorized personnel only.

Limits and open questions

It remains unknown whether this vulnerability has been utilized in specific ransomware campaigns. Additionally, while CISA provides a remediation deadline for federal agencies (2026-05-08), this date serves as a risk indicator rather than a mandatory requirement for private sector organizations. Residual risk persists if the product is continued in use without available vendor mitigations; in such cases, the only definitive reduction in exposure is to discontinue use of the affected software.
