MagicINFO 9 Server - Path Traversal (CVE-2025-4632)

CVE-2025-4632 is a critical vulnerability in Samsung MagicINFO 9 Server prior to version 21.1052 that allows attackers to write arbitrary files as system authority due to improper restriction of pathnames. This flaw could be exploited remotely to gain full control over the server, potentially leading to data breaches, system compromise, or the deployment of malicious code.

CrowdSec has been tracking this vulnerability and its exploits since 3rd of September 2025.

CrowdSec network data shows that most actors exploiting CVE-2025-4632 rely on broad, untargeted scans with minimal filtering. The activity is largely automated and opportunistic in nature. CrowdSec data also reveals a clear uptick in attacks involving CVE-2025-4632 over the past week. Activity is above the usual baseline, suggesting growing attention from attackers. This may reflect rising awareness, recent exploit releases, or expanded targeting efforts.

Attackers exploit the /MagicInfo/servlet/SWUpdateFileUploader endpoint to upload files outside the intended directory by abusing the fileName parameter with path traversal sequences, enabling remote code execution on Samsung MagicINFO 9 Server systems. Subsequent requests to /MagicInfo/<filename>.html are used to access the uploaded malicious files.
