CVE Alert: CVE-2025-11420 – code-projects – E-Commerce Website

Risk verdict: High risk due to remote, unauthenticated SQL injection with publicly available exploit, enabling potential data access and manipulation.

Why this matters: The flaw can expose customer data and order details, risking financial loss, fraud, and reputational damage. Compromise of the e‑commerce backend may enable data alteration, downtime, and supply-chain disruption, especially for transactional sites handling payments and PII.

Most likely attack path: An automated attacker can exploit the web interface without user interaction to run arbitrary SQL against the database. The flaw’s CVSS indicators point to low preconditions and no UI requirement, implying quick weaponisation and potential broad impact on data integrity, confidentiality, and availability within the compromised scope.

Who is most exposed: Public-facing e‑commerce deployments, particularly small to mid-size sites on shared or low‑segregation hosting with PHP–MySQL stacks, are at greatest risk. Exposed admin/order endpoints often attract automated probes and low-friction exploitation.

Detection ideas:

• Unusual or suspicious HTTP inputs resembling SQL payloads in order-related requests.
• Database errors or hints of SQL syntax in responses or logs.
• Spikes in 500s or failed queries linked to the affected endpoint.
• WAF IPS alerts for SQL injection signatures.
• Out-of-band data exfiltration indicators or unexpected query patterns.

Mitigation and prioritisation:

• Apply vendor fix or upgrade to patched version; validate in staging before prod.
• Enforce parameterised queries and prepared statements; away from dynamic string concatenation.
• Minimise error disclosure; suppress verbose DB errors in production.
• Enforce least privilege for DB credentials; restrict user permissions and network access.
• Enable and tune WAF/IPS rules for SQL injection; monitor for related IOC activity.
• Change-management: deploy patch promptly with verification and rollback plan.
• If KEV true or EPSS ≥ 0.5, treat as priority 1. If data indicates otherwise, maintain high-priority remediation with a tight patch window.
