RC4 Cipher Vulnerabilities in Multiple NetApp Products

circle-check-alt This advisory should be considered the single source of current, up-to-date, authorized and accurate information from NetApp regarding Full Support products and versions.

The email subscription feature has been temporarily disabled.

Summary

Multiple NetApp Products use the RC4 algorithm in the TLS and SSL protocols. The RC4 cipher has a weakness that may allow attackers to conduct plaintext recovery which could result in unauthorized information disclosure. Fixed versions of NetApp products will either disable RC4 ciphers or introduce an option to disable them to prevent this type of attack. This bulletin will be updated as additional information becomes available.

Impact

Exploitation of this vulnerability may result in unauthorized disclosure of information.

Workarounds

  • Data ONTAP operating in 7-Mode beginning with version 8.2.3: the command 'options rc4.enable off' will disable RC4 cipher support in the TLS and SSL protocols over HTTPS and FTPS connections. The option defaults to 'on'.
  • clustered Data ONTAP 8.2.2RC1 through 8.3.x: enable OpenSSL FIPS 140-2 compliance mode to disable RC4 cipher support:
    ::*> system services web modify -ssl-fips-enable true
    
  • clustered Data ONTAP 9.x:
    • Enable FIPS 140-2 compliance mode to disable RC4 cipher support in cluster-wide control plane interfaces:
      ::*> security config modify -is-fips-enabled true	
    • Default ciphers can also be disabled in the 9.x versions of ONTAP using the '-supported-ciphers' option with the 'security config' command:
      ::*> security config modify -supported-ciphers CURRENT_CIPHER_STRING:!RC4
      
  • NetApp SANtricity SMI-S Provider: disable weak ciphers using the command "cimconfig -s sslCipherSuite="HIGH" -p" followed by a restart of the Pegasus CIM Object Manager Service.
  • NetApp AltaVault: remove RC4 as a supported cipher by adding “:-RC4” to the SSLCipherSuite list as follows:
    	(config) # show web ssl cipher
    	  Apache SSL cipher string: HIGH:-aNULL:-kKRB5:-MD5
    	(config) # web ssl cipher 'HIGH:-aNULL:-kKRB5:-MD5:-RC4'  
  • Element Software and NetApp HCI nodes: to disable the use of RC4 ciphers contact technical support for assistance with applying a D Patch.
