Prior to 10.6.4, Symantec Messaging Gateway may be susceptible to a path traversal attack (also known as directory traversal). These types of attacks aim to access files and directories that are stored outside the web root folder. By manipulating variables, it may be possible to access arbitrary files and directories stored on the file system including application source code or configuration and critical system files.

The Symantec Messaging Gateway can encounter an issue of remote code execution, which describes a situation whereby an individual may obtain the ability to execute commands remotely on a target machine or in a target process.

The management console on Symantec Messaging Gateway (SMG) Appliance devices before 10.6.1 allows local users to discover an encrypted AD password by leveraging certain read privileges.

Cross-site scripting (XSS) vulnerability in brightmail/setting/compliance/DlpConnectFlow$view.flo in the management console in Symantec Messaging Gateway 10.x before 10.5.2 allows remote attackers to inject arbitrary web script or HTML via the displayTab parameter.

Multiple directory traversal vulnerabilities in the management console in Symantec Messaging Gateway (SMG) 9.5.x allow remote authenticated users to read arbitrary files via a .. (dot dot) in the (1) logFile parameter in a logs action to brightmail/export or (2) localBackupFileSelection parameter in an APPLIANCE restoreSource action to brightmail/admin/restore/download.do.
