An improper access control flaw was found in Candlepin. An attacker can create data scoped under another customer/tenant, which can result in loss of confidentiality and availability for the affected customer/tenant.

Candlepin before 0.7.24, as used in Red Hat Subscription Asset Manager before 1.2.1, does not properly check manifest signatures, which allows local users to modify manifests.

Candlepin allows remote attackers to obtain sensitive information by obtaining Java exception statements as a result of excessive web traffic.

Red Hat Satellite was affected by an improper authentication in which few factors allow for someone to use the SCA (simple content access) certificate for authentication with Candlepin. The SCA certificates are purposed only for authorizing content access against the CDN (or Pulp in case of Satellite).

Devan Goodwin <dgoodwin> reports:

We have identified a fairly serious security issue in previous, or upgraded versions of Subscription Asset Manager (SAM).

The issue was caused by an extremely insecure authentication mode in the candlepin project, which was mistakenly enabled by default if no setting was specified in the config file.
