Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a vulnerability in a drift reconciliation technology where it may improperly trust external instructions. Attackers could potentially leverage this to execute unintended operations. The primary concern is to confirm if this technology is in use and if it is exposed to untrusted inputs.
- Software accepts bad instructions without checking.
- Crucial to verify if this technology is used.
- Confirm relevance and assess potential exposure.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by supplying a malicious "execute plan" to a system using vulnerable software. This plan bypasses security checks, allowing the attacker to perform unauthorized reconciliation operations.
- Untrusted input accepted by the system.
- Malicious execute plans trigger unsafe operations.
- High risk of unauthorized system manipulation.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an attacker to bypass security checks and execute malicious operations when processing untrusted reconciliation input. When supported by the advisory, this could impact system data and service behavior.
- System data and service behavior are at risk.
- Malicious execute plans could bypass security.
- Unsafe reconciliation operations may occur.
Operational Fix
Recommended remediation, mitigation, and detection steps
The `@hulumi/drift` tool's insufficient validation of execute plans requires immediate attention. Application owners, potentially alongside infrastructure or platform teams, must identify all instances of this software, determine their exposure and criticality, and then coordinate remediation. This involves understanding which systems process externally supplied plans and ensuring those plans are from trusted sources before any reconciliation actions occur.
- Identify affected @hulumi/drift instances.
- Confirm reachability and business criticality.
- Plan risk-based remediation activities.
