Technical details

A local privilege escalation vulnerability exists in Samsung MagicINFO 9 Server versions prior to 21.1091.1 due to incorrect default permissions (CWE-276). The vulnerability allows a local attacker with low-privileged access to escalate their privileges to a higher level, potentially gaining full system authority. The attack vector is local, requiring the attacker to have existing access to the server environment. Samsung has addressed this issue in the December 2025 security update by modifying the verification logic of the input and correcting permission settings.
