Doc Text:
It was discovered that a world-readable log file, belonging to the Candlepin component of Red Hat Satellite 6.4, leaked the credentials of the Candlepin database. A malicious user with local access to a Satellite host can use those credentials to modify the database and prevent Satellite from fetching package updates, thus preventing all Satellite hosts from accessing those updates.

Description Laura Pardo 2019-03-28 20:17:32 UTC
A vulnerability was found in the way Satellite 6 installer logs the calls to Candlepins cpdb. The /var/log/candlepin/cpdb.log log file permissions allows a non privileged user to read credentials information from the log files.

Comment 4 Richard Maciel Costa 2019-04-03 19:48:24 UTC

Remove world readable permission from /var/log/candlepin/cpdb.log, by executing the following on the console of the machine where Red Hat Satellite is installed, as root:
chmod o-r /var/log/candlepin/cpdb.log
