Samsung MagicINFO 9 Server Path Traversal Vulnerability
Samsung · MagicINFO 9 Server
The flaw is an improper limitation of a pathname to a restricted directory in the Samsung MagicINFO 9 Server product. It affects versions of MagicINFO 9 Server before 21.1052 and is a path traversal weakness. An attacker who can reach the server over the network, with no authentication or user interaction required, can write arbitrary files with system authority.
Improper limitation of a pathname to a restricted directory vulnerability in Samsung MagicINFO 9 Server version before 21.1052 allows attackers to write arbitrary file as system authority.
