Name of the Vulnerable Software and Affected Versions Veritas NetBackup versions 8.0 and earlier Veritas NetBackup Appliance versions 3.0 and earlier

Description The issue is related to insufficient access control, allowing unauthenticated file copy and arbitrary remote command execution. This can be achieved by exploiting the bprd process, potentially enabling an attacker to copy any file and execute commands in a privileged mode.

Recommendations For Veritas NetBackup versions 8.0 and earlier, update to a version later than 8.0 to resolve the issue. For Veritas NetBackup Appliance versions 3.0 and earlier, update to a version later than 3.0 to resolve the issue. As a temporary workaround, consider restricting access to the bprd process to minimize the risk of exploitation.
