Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid authenticated session on the target platform - specifically a low-privilege user account (e.g., a registered shopper). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.1 accurately reflects limited real-world impact: integrity and availability impacts are both Low (VI:L, VA:L) with zero confidentiality exposure (VC:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a low-privilege account on the target platform running Multi-Vendor Online Grocery Management System 1.0, then crafts HTTP requests to the cancel_order endpoint in classes/Master.php, substituting arbitrary order IDs (belonging to other customers) in the request parameters. Because the server performs no ownership validation, the orders are cancelled successfully, disrupting vendor fulfillment operations and potentially causing financial and reputational harm to the platform. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the fix version is not confirmed from the available references. … Detailed patch versions, workarounds, and compensating controls in full report. |
