The server can restore user files and generate reports detailing installed hardware, software, and data files on each client with a valid user account on the server. There exists a buffer overflow vulnerability in Computer Associates BrightStor ARCserve Backup for Laptops and Desktops. The flaw is due to an insufficient checks of user supplied data inside requests sent to the backup server. A remote unauthenticated attacker may leverage this vulnerability to inject and execute arbitrary code on the target host with System level privileges.
