Summary
A flaw was found in insights-core where the password redaction layer fails to recognize credentials not keyed under the literal string 'password'. This allows SSSD LDAP bind passwords (ldap_default_authtok) and Pacemaker fence device credentials to be included in cleartext in archives uploaded to console.redhat.com.
The default insights-client configuration is affected, leading to potential exposure of sensitive credentials to individuals with access to these uploaded archives. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
Weakness: CWE-312. Affected Red Hat products: Pen Drive Powered by Red Hat Lightspeed; Red Hat Certification Program for Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9.
Red Hat lists Red Hat Satellite 6 as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: insights-core.

Mitigation checklist
- Exclude sssd_config, sssd_conf_d, and cib_xml via /etc/insights-client/file-redaction.yaml, or add keyword/pattern redaction covering ldap_default_authtok and fence passwd/password XML forms, until a patched insights-core is available.
