Veritas Backup Exec for Windows Servers contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a remote user sends a CONNECT_CLIENT_AUTH request with a hardcoded password value to trigger the flaw. If successful, the flaw will disclose arbitrary files that are accessible via the Windows system account, resulting in a loss of confidentiality.
