Description
A flaw was found in Dogtag PKI, as used by FreeIPA's certificate authority component. The certificate profile import functionality does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit Dogtag's ExternalProcessConstraint mechanism to execute arbitrary commands with attacker-controlled environment variables, achieving code execution as the pkiuser account.

Remediation

Vendor Workaround

Until a fixed package is available, restrict membership in CA Administrator and equivalent roles to fully trusted operators, and audit certificate profile import operations for unexpected or unrecognized profile content. Review any custom ExternalProcessConstraint executable configuration in Dogtag for unnecessary exposure.
