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.
