Summary

Candlepin, the component in Red Hat Satellite 6, has a central authorization filter that grants access when any one of several verified parameters is accessible instead of requiring access to all of them. An authenticated attacker with low privileges who can access the first referenced object can reach subsequent objects (CWE-863). If the target identifiers are known, the attacker can read consumer information and modify entitlements and subscription resources, including across organizations.

Description from the CNA

A flaw was found in Candlepin. The central authorization filter incorrectly grants access when any one of multiple @Verify-annotated parameters is accessible, instead of requiring access to every verified entity. A low-privilege authenticated attacker who can access the first referenced object can bypass authorization checks on subsequent objects. When target resource identifiers are known, this can enable unauthorized disclosure of consumer information and unauthorized modification of entitlements and related subscription resources, including across organizations.
