Attack Chain

This attack chain describes the potential exploitation of the vulnerability where @hulumi/drift accepts externally supplied execute plans without proper validation.

1. An attacker crafts a malicious execute plan designed to manipulate the reconciliation process.
2. The attacker supplies the crafted execute plan to an application using a vulnerable version of @hulumi/drift.
3. @hulumi/drift, lacking sufficient provenance checks, accepts the externally supplied execute plan.
4. The application processes the malicious execute plan, treating it as a trusted input.
5. The reconciliation process is influenced by the attacker’s crafted plan, leading to unintended consequences.
6. The attacker achieves their objective, which could include data manipulation, privilege escalation, or denial of service, depending on the application’s functionality and the scope of the reconciliation process.

Impact

Successful exploitation of this vulnerability could lead to a compromise of the integrity of applications using the vulnerable versions of @hulumi/drift. By supplying malicious execute plans, attackers can manipulate the reconciliation process, potentially leading to unauthorized data modification or unintended system behavior. This could have significant consequences for applications relying on the integrity of the reconciliation process.

Recommendation

• Upgrade @hulumi/drift to version 1.3.2 or later to remediate the vulnerability as advised in the GitHub Advisory GHSA-2ffm-hxrq-qqmm.
• Implement additional input validation and sanitization measures within applications using @hulumi/drift to further mitigate the risk of malicious input.
