Comment 2 Vincent Danen 2013-08-08 19:29:39 UTC
It was discovered that the luci configuration file was generated in an insecure manner.  Because the configuration is generated on-demand via the luci initscript from a template, and because it is created and then has its permissions changed, the /var/lib/luci/etc/luci.ini file contents are briefly exposed to local users due to world-readable permissions.
