ebics-java-client: Missing Cryptographic Step
CVE-2022-1279 is a high-severity missing cryptographic step vulnerability in ebics-java-client from Ebics-java, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.2 as the first without the flaw, so updating ebics-java-client to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update ebics-java-client to 1.2 or a later version.
- Update Ebics Java to 1.2 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability in the encryption implementation of EBICS messages in the open source librairy ebics-java/ebics-java-client allows an attacker sniffing network traffic to decrypt EBICS payloads. This issue affects: ebics-java/ebics-java-client versions prior to 1.2.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Missing Cryptographic Step
The product does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than advertised by the algorithm.
