-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Setting services to debug mode can also set Pecan to debug - ---
### Summary ### When debug mode is set for a service using Pecan (via --debug or CONF.debug=True) Pecan is also set to debug. This can result in accidental information disclosures. ### Affected Services / Software ### Blazar, Ceilometer, Cue, Gnocchi, Ironic, Kite, Libra, Pecan, Tuskar ### Discussion ### Although it's best practice to run production environments with debugging functionality disabled, experience shows us that many deployers choose to run OpenStack with debugging enabled to aid with administration and fault finding. When Pecan is running in debug mode, the following capabilities are made available to anyone who can interact with the API service: * Retrieve a stack trace of failed Pecan calls * Retrieve a full list of environment variables containing potentially sensitive information such as API credentials, passwords etc. * Set an execution breakpoint which hangs the service with a pdb shell, resulting in a denial of service ### Recommended Actions ### At time of writing, Ceilometer, Gnocchi and Ironic have released fixes. Deployers are encouraged to apply these fixes (see launchpad bug in References) in their clouds. For services that do not have a fix, or where fixes cannot be applied in existing deployments, we advise not using the debug configuration for affected services in production environments. ### Contacts / References ### This OSSN : https://wiki.openstack.org/wiki/OSSN/OSSN-0046 Original LaunchPad Bug : https://bugs.launchpad.net/ironic/+bug/1425206 OpenStack Security ML : [email protected] OpenStack Security Group : https://launchpad.net/~openstack-ossg Pecan : http://www.pecanpy.org/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJVULpuAAoJEJa+6E7Ri+EVdMUIAKmzQkm8CZp9E5q+5tuHh7ix n3aekuYYcQ0hqk/KG8yx7dd6966Rq/EOw7bjM9rOXs9M0aLOCoyarGI9ZwrrAe86 K0VwS3E5fqX3VmiRbDBXraDlEJn8sdS8WwAApvHwlv7yEK+z+YggDhhtGvnJyQe2 rxXeZIVFPsY1bnSFtPPsUqfFvFiXSUbK3MvAEJ2USthPbS8arQbWEbBzZ60qLVhE 4tJaCFaMTkCXpIQ1ndAv63/jTQpq2N0PiaW2BPvaAGZUmUakMgCKrSwRnZ4nQw7s NKNdmuBMTS5TNv6H9d0NixfO8NB7rNPcUm9Raon3GqnZM2mVFhc+6z4SaQUSe/I= =eKSs -----END PGP SIGNATURE----- _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
