Technical Details for CVE-2025-4632

Vulnerability Analysis

The vulnerability arises from an improper limitation of a pathname to a restricted directory within the Samsung MagicINFO 9 Server. An attacker could leverage this flaw to perform a path traversal attack, allowing them to escalate privileges by writing arbitrary files as a system authority.

Root Cause

The root cause is the improper validation of pathnames, leading to directory traversal.

Attack Vector

Network-based exploitation allows unauthenticated attackers to send crafted requests to the vulnerable server, facilitating arbitrary file write operations.

bash

# Example exploitation code (sanitized)
curl -X POST \
  http://vulnerable-server.com/endpoint \
  -d 'payload=../../../../../../etc/passwd%00'

Detection Methods for CVE-2025-4632

Indicators of Compromise

Unauthorized file creation or modification in restricted directories
Suspicious server responses indicating successful writes
Logs showing unexpected pathname requests

Detection Strategies

Monitor network traffic for abnormal POST requests containing '/../'. Utilize file integrity monitoring to detect unauthorized file changes in critical directories. Employ SIEM solutions to correlate logs and detect anomalies.

Monitoring Recommendations

Configure network-based intrusion detection systems (NIDS) to flag suspicious requests with path traversal patterns. Use endpoint monitoring for unauthorized file changes and privilege escalation attempts.

How to Mitigate CVE-2025-4632

Immediate Actions Required

Upgrade to Samsung MagicINFO 9 Server version 21.1052 or later
Implement strict input validation and sanitization
Monitor and restrict access to sensitive directories

Patch Information

Samsung has released a security patch addressing this vulnerability. See Samsung Security Updates for details.

Workarounds

Limit exposure by implementing network segmentation and firewalls to prevent external access to the vulnerable server. Temporarily disable affected services if applicable.
