BrightStor ARCserve Backup r11.1 delivers leading backup and restore
protection for all classes of Windows, NetWare, Linux and UNIX servers,
as well as Windows, Mac OS X, Linux, UNIX, AS/400 and VMS client
Remote exploitation of a design flaw in Computer Associates
International Inc's BrightStor ARCserve Backup UniversalAgent for UNIX
may allow attackers to browse the file system.
The vulnerability specifically exists due to hard coded credentials
being left in the production release of the UniversalAgent for UNIX. An
attacker may use the following credentials to gain read access to the
remote file system:
The BrightStor software uses a network agent to perform backups on
nodes across the network. Typically, the agent service requires either
administrative credentials or a node-specific password and is capable
of backing up files and remotely executing commands. The agent will
listen on TCP and UDP ports 6051 by default and is installed on every
node that the BrightStor server is configured to backup.
Computer Associates BrightStor ARCserve Backup r11.1 for Linux and UNIX
have been confirmed vulnerable.
Employ firewalls, access control lists or other TCP/UDP restriction
mechanism to limit access to the backup port on affected systems and
services. The login credentials are sent in cleartext and may also be
used to detect connections from attackers.
