Title
Pki-core: dogtag/pki: certprofile-import allows code execution via unsanitized profile content (externalprocessconstraint)
Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
