Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in salt. Invalid eauth credentials and tokens are not handled correctly when calling Salt SSH via the salt-api which could allow an attacker to bypass authentication and gain access to restricted information or to possibly conduct further attacks. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Comment 1 Guilherme de Almeida Suckevicz 2020-11-06 17:33:13 UTC
Created salt tracking bugs for this issue:

Affects: fedora-all [bug 1895455]

Comment 2 Bryce Larson 2020-11-06 17:43:25 UTC
This was already fixed in salt 3001.3 which has already been released in fedora 31 and 32, and 3002.1 which has been released in 33 and rawhide.

Mitigation:

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Comment 9 Eric Christensen 2020-11-09 18:41:26 UTC
Statement:

Red Hat Ceph Storage 2 shipped salt for the usage of Red Hat Storage Console 2 (RHSCON-2), which required salt to administrate ceph nodes. RHSCON-2 has reached End Of Life, hence salt is no longer used and supported. Therefore, the salt package provided by Red Hat Ceph Storage 2 has been marked as 'will not fix'.
