Incorrect default permissions issue exists in Security Point (Windows) of MaLion prior to Ver.5.3.4. If this vulnerability is exploited, an arbitrary file could be placed in the specific folder by a user who can log in to the system where the product's Windows client is installed. If the file is a specially crafted DLL file, arbitrary code could be executed with SYSTEM privilege.

Security Point (Windows) of MaLion and MaLionCloud contains a heap-based buffer overflow vulnerability in processing Content-Length. Receiving a specially crafted request from a remote unauthenticated attacker could lead to arbitrary code execution with SYSTEM privilege.

MaLion for Windows and Mac versions 3.2.1 to 5.2.1 uses a hardcoded cryptographic key which may allow an attacker to alter the connection settings of Terminal Agent and spoof the Relay Service.

MaLion for Windows 5.2.1 and earlier (only when "Remote Control" is installed) and MaLion for Mac 4.0.1 to 5.2.1 (only when "Remote Control" is installed) allow remote attackers to bypass authentication to execute arbitrary commands or operations on Terminal Agent.

MaLion for Mac 4.3.0 to 5.2.1 does not properly validate certificates, which may allow an attacker to eavesdrop on an encrypted communication.

SQL injection vulnerability in the MaLion for Windows and Mac 5.0.0 to 5.2.1 allows remote attackers to execute arbitrary SQL commands via Relay Service Server.

MaLion for Windows and Mac 5.0.0 to 5.2.1 allows remote attackers to bypass authentication to alter settings in Relay Service Server.
