1) Cryptographic issues (CVE-ID: CVE-2019-1547)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to insufficient enforcement of side channel resistant code paths. A remote attacker with ability to create a large number of signatures, where explicit parameters with no co-factor is present, can force the application to fall back to non-side channel resistant code pathsduring ECDSA signature operation and perform full key recovery.

Successful exploitation of the vulnerability may allow an attacker to decrypt communication between server and client.
