Security Advisory

1) Cache Attacks

Risk: Medium

CVSSv3:
7.3 [CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:H/E:P/RL:O/RC:C] [PCI]

CVE-ID:
CVE-2018-12404

CWE-ID:
CWE-300 – Channel Accessible by Non-Endpoint (‘Man-in-the-Middle’)

Exploit availability:
No

Description

The vulnerability allows a remote attacker to perform a downgrade attack on the server and decrypt private keys on the target system.

The vulnerability exists due to a core weakness in TLS that relates to the handshaking of the session key which is used within the tunnel during parallelisation of thousands of oracle queries that occurs using a cluster of TLS servers which share the same public key certificate. A remote attacker can mount a microarchitectural side channel attack against a vulnerable implementation, obtain a network man-in-the-middle position, obtain the relevant data to sign and trigger the victim server to decrypt ciphertexts chosen by the adversary to perform a downgrade attack.

Mitigation

Install update from vendor’s website.
