CVE-2018-1466

Vulnerability

IBM SAN Volume Controller, IBM Storwize, IBM Spectrum Virtualize, and IBM FlashSystem products running versions 6.1, 6.2, 6.3, 6.4, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.6.1, 7.7, 7.7.1, 7.8, 7.8.1, 8.1, and 8.1.1 employ cryptographic algorithms that are weaker than expected. This weakness could allow an attacker to decrypt highly sensitive information that is protected by these algorithms.

Exploitation

The description does not specify the required attacker capabilities or the precise attack vector. The vulnerability lies in the cryptographic algorithm strength, so exploitation would involve an attacker obtaining encrypted data (e.g., via network interception or access to stored data) and then decrypting it using the weak algorithms.

Impact

An attacker who successfully exploits this vulnerability could decrypt highly sensitive information, leading to a loss of confidentiality. The scope of compromise is limited to data that was encrypted using the weak algorithms.

Mitigation

The available references do not disclose a specific fix for CVE-2018-1466. Users should monitor IBM's security advisories and contact IBM support for guidance on updates or workarounds.
