CVE Alert: CVE-2025-12378 – code-projects – Simple Food Ordering System

Risk verdict

High risk due to remote, unauthenticated file upload weakness with a publicly available PoC; treat as priority to patch promptly (pending KEV/EPSS confirmation).

Why this matters

The unrestricted upload flaw in addproduct.php enables an attacker to push arbitrary files to the server, potentially leading to webshell deployment, defacement, or further compromise of the hosting environment. With no user interaction or privileges required, an attacker could chain this into sustained access or data exposure, impacting availability and integrity of order-processing functions.

Most likely attack path

• Attack vector: network-based, no authentication, no user interaction required.
• Preconditions: none beyond access to the vulnerable endpoint; low complexity means automated tools can probe.
• Potential progression: uploaded payload could overwrite or write code in the webroot, enabling remote command execution and lateral movement within the app or host.

Who is most exposed

Likely exposed in small-to-medium deployments hosting the Simple Food Ordering System on shared or misconfigured PHP stacks, especially where uploads are not correctly sandboxed or validated.

Detection ideas

• Spike in POST requests to /addproduct.php with unusual or large photo payloads.
• Uploads containing PHP/ PHP-like scripts or executable content in the uploads folder.
• New or modified files in webroot with executable permissions or shell-like names.
• Anomalous file-creation timestamps or repeated attempts from single IPs/regions.
• Logs showing bypassed content-type checks or terse error responses on upload attempts.

Mitigation and prioritisation

• Apply vendor patch or upgrade to fixed release; validate fix in test environment before prod.
• Implement strict file-type allowlists, reject executable extensions, and store uploads outside the webroot; rename uploaded files.
• Enforce authentication/CSRF protection on addproduct.php; apply input validation on the photo parameter.
• Add WAF rules to block suspicious upload patterns and large multipart requests.
• Improve logging and alerting for file-upload anomalies; conduct a targeted rollback plan if instability occurs.
• If KEV is true or EPSS ≥ 0.5, treat as priority 1; otherwise aim for priority 2 with expedited remediation.
