IBM Integrated Analytics System update for OpenSSL

1) Inadequate Encryption Strength

EUVDB-ID: #VU68116

Risk: Medium

CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:F/RL:O/RC:C]

CVE-ID: CVE-2022-3358

CWE-ID: CWE-326 - Inadequate Encryption Strength

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to an error in openssl implementation when handling legacy custom ciphers with NID_undef passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions. Under certain conditions openssl can fail to select a proper cipher and use NULL instead, which corresponds to sending data in plain text.

Note, applications are only affected by this issue if they call EVP_CIPHER_meth_new() using NID_undef and subsequently use it in a call to an encryption/decryption initialisation function.

Mitigation

Install update from vendor's website.
