CVE-2020-13867 [MEDIUM] CWE-276 targetcli: weak permissions for /etc/target and backup files
targetcli: weak permissions for /etc/target and backup files
Open-iSCSI targetcli-fb through 2.1.52 has weak permissions for /etc/target (and for the backup directory and backup files).
An access flaw was found in targetcli, where the `/etc/target` and underneath backup directory/files were world-readable. This flaw allows a local attacker to access potentially sensitive information such as authentication credentials from the /etc/target/saveconfig.json and backup files. The highest threat from this vulnerability is to confidentiality.
Statement: The version of targetcli shipped with Red Hat Ceph Storage 3 sets the world-readable permissions for `/etc/target` and `/etc/target/backup` directory that store the sensitive information, hence affected by this vulnerability.
Mitigation: $ chm
