Dogtag PKI Code Execution via Profile Import

Publication date: 2026-09-08

Last updated on: 2026-09-08

Assigner: redhat-SADP

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.

Executive Summary

CVE-2026-76561 is a flaw in Dogtag PKI, used by FreeIPA's certificate authority. The vulnerability exists in the certificate profile import feature, which does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit this to execute arbitrary commands via Dogtag's ExternalProcessConstraint mechanism, achieving code execution as the pkiuser account.

Impact Analysis

This vulnerability allows an attacker with CA Administrator privileges to execute arbitrary commands on the system as the pkiuser account. In some environments, this could escalate to full root access. The attack requires existing privileged access, so it does not affect unauthenticated users.

Compliance Impact

This vulnerability could lead to unauthorized code execution, potentially compromising confidentiality, integrity, and availability of sensitive data. Organizations handling regulated data (e.g., under GDPR or HIPAA) may face compliance violations if this flaw is exploited, resulting in data breaches or unauthorized access to protected information.

Mitigation Strategies

Restrict membership in CA Administrator and equivalent roles to fully trusted operators. Audit certificate profile import operations for unexpected content. Review custom ExternalProcessConstraint executable configurations in Dogtag for unnecessary exposure.
