Detailsinfo

A vulnerability, which was classified as problematic, was found in Red Hat Ceph Storage (the affected version is unknown). This affects an unknown code. The manipulation with an unknown input leads to a inadequate encryption vulnerability. CWE is classifying the issue as CWE-326. The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. This is going to have an impact on confidentiality. The summary by CVE is:

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

The weakness was shared 08/26/2022 by Red Hat as 54006. The advisory is shared at tracker.ceph.com. This vulnerability is uniquely identified as CVE-2021-3979 since 11/19/2021.
