Description
A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw -- intended to require Administrator-level profiles.create permission -- to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy.

Remediation

Vendor Workaround

There is no way to mitigate this issue other than applying an update once available. As a partial mitigation, limiting membership in the Certificate Manager Agents group to trusted users reduces exposure, since exploitation requires an authenticated credential in that role.
