Technical details

A path traversal vulnerability (CWE-22) exists in Samsung MagicINFO 9 Server versions prior to 21.1052. The flaw stems from improper limitation of a pathname to a restricted directory, which can be exploited by a remote, unauthenticated attacker via the network. By sending specially crafted requests, an attacker can bypass directory restrictions to write arbitrary files to the underlying operating system. Successful exploitation grants the attacker the ability to execute code or modify system files with system-level privileges. This vulnerability has been observed being exploited in the wild and is included in the CISA Known Exploited Vulnerabilities (KEV) catalog.
