Applies to

  • ONTAP tools for VMware vSphere (OTV) 9.12
  • SSH (Secure Shell)

Issue

SSH vulnerabilities highlighted:

  1. Ciphers using CFB or OFB: These are considered uncommon and deprecated due to vulnerabilities when compared to newer cipher chaining modes such as CTR or GCM
  2. RC4 cipher (arcfour, arcfour128, arcfour256): The RC4 cipher is no longer considered secure and exhibits cryptographic bias
  3. Ciphers with a 64-bit block size (DES, 3DES, Blowfish, IDEA, CAST): These ciphers may be vulnerable to birthday attacks (Sweet32)
  4. Key exchange algorithms using DH group 1 (diffie-hellman-group1-sha1, diffie-hellman-group14-sha1,gss-group1-sha1-*): DH group 1 uses a 1024-bit key size, which is considered too short and vulnerable to Logjam-style attacks
