Symantec NetBackup Communications Setup Elevation of Privilege
Note: Product versions prior to those listed above are NOT supported. Customers running legacy product versions should upgrade and apply available updates. Details
During the normal process of an administrative login, the Symantec Veritas NetBackup server communicates with the client via the Veritas network daemon, vnetd. This communication process does not properly sanitize server-supplied data during initial communications setup. This could allow a non-privileged user with access to the targeted host's local network, to insert arbitrary code of their choice on the system which could then potentially execute on the system with administrative privileges. Exploitation could possibly result in memory corruption and denial of service or, if successfully exploited, could potentially allow a malicious user to gain administrative privileges on the targeted computer.
Symantec engineers have verified that the vulnerability exists in the supported versions of Symantec Veritas NetBackup listed in the table above. Updates have been released to resolve the issue.
Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue.
