Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a critical vulnerability in Pimcore, an open-source data and experience management platform. The issue allows authenticated users to inject malicious code, potentially leading to arbitrary code execution and SQL injection. The primary concern is confirming if your organization uses this platform and if the affected versions are in use.
- Injects code into data objects.
- Allows code execution and data alteration.
- Confirm Pimcore usage and exposure.
Attack Path
How an attacker could exploit the issue
An attacker could gain the ability to execute arbitrary code or manipulate the database by exploiting a vulnerability in Pimcore's class-definition import functionality. This requires an authenticated user with object permissions to submit specially crafted input to an API endpoint. When objects of the affected class are later created, the injected PHP code runs, or malicious SQL statements are executed against the database.
- Authenticated user with object permissions.
- Importing class definitions with malicious input.
- Arbitrary code execution and SQL injection.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an authenticated user with specific permissions to inject malicious code into PHP files or execute arbitrary SQL commands by manipulating class definitions. This could lead to the execution of attacker-controlled code when objects of a modified class are created, or unauthorized modifications to the database schema.
- Affected asset: Customizable PHP classes and database schema.
- Exposure: Injecting malicious code into class definitions.
- Consequence: Arbitrary code execution and data integrity compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
Real-world remediation likely falls to the platform or application owners managing the Pimcore instance, supported by security teams for exposure analysis and infrastructure teams for patching or configuration. The first practical step is to identify all deployed Pimcore instances, determine their reachability and criticality, and pinpoint the accountable owner for each. Subsequently, a risk-based remediation plan should be developed, which may involve coordinating with the vendor, planning maintenance windows, or implementing temporary mitigations.
- Platform owners should manage the issue.
- Verify asset reachability and criticality.
- Plan remediation based on assessed risk.
