CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-4632 is a critical-severity Path Traversal (CWE-22) vulnerability in Samsung Magicinfo 9 Server. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-4632 is a path traversal vulnerability (CWE-22) affecting Samsung MagicINFO 9 Server versions prior to 21.1052. The flaw stems from improper limitation of pathnames to a restricted directory, enabling unauthenticated remote attackers to write arbitrary files with system-level privileges.
An attacker can exploit the issue over the network without authentication or user interaction to upload and execute malicious files on the server, potentially leading to full system compromise including data exfiltration, persistence, or lateral movement within the environment.
Samsung has published remediation guidance in its May 2025 security updates, directing customers to upgrade MagicINFO 9 Server to version 21.1052 or later. The vulnerability is also listed in CISA's Known Exploited Vulnerabilities catalog, confirming observed in-the-wild exploitation.
The associated EPSS score has reached a peak of 0.4916 with a current value of 0.4260, reflecting substantial and sustained exploitation interest following public disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
