The web console in Symantec Altiris Notification Server 6.0.x before 6.0 SP3 R12 uses a hardcoded key that can decrypt SQL Server credentials and certain discovery credentials, and stores this key on the Notification Server machine, which allows local users to obtain sensitive information and possibly execute arbitrary code by decrypting and using these credentials.
The Altiris eXpress NS SC Download ActiveX control in AeXNSPkgDLLib.dll, as used in Symantec Altiris Deployment Solution 6.9.x, Notification Server 6.0.x, and Symantec Management Platform 7.0.x exposes an unsafe method, which allows remote attackers to force the download of arbitrary files and possibly execute arbitrary code via the DownloadAndInstall method.
