CVE Alert: CVE-2025-11471 – SourceCodester – Hotel and Lodge Management System

Risk verdict

High risk: remote SQL injection with a publicly disclosed PoC and ongoing advisory coverage; remediation should be prioritised.

Why this matters

Attackers could exfiltrate or alter customer and reservation data, potentially impacting payments and guest records. The public PoC and advisory presence raise the likelihood of opportunistic abuse and automated exploitation, risking data loss, service disruption, and reputational damage.

Most likely attack path

Remote attacker sends unauthenticated requests to the vulnerable parameter in the affected PHP page, triggering SQL injection. With PR:N, UI:N, AC:L and AV:N, exploitation requires no user interaction and low access complexity. Successful exploitation could lead to data disclosure or modification within the database; lateral movement is unlikely given the lack of elevated privileges, but data exfiltration is plausible.

Who is most exposed

Typically deployed in small to mid-size environments, often internet-facing on legacy installations of web-based hotel management software; default configurations and outdated patches increase exposure.

Detection ideas

• Look for anomalous SQL-like payloads in web server logs targeting edit_customer.php (e.g., unusual quotes, UNION SELECT patterns).
• Increased database error messages or long-running queries from that endpoint.
• Unusual data access patterns or mass data exfiltration indicators.
• IDS/IPS signatures for SQL injection attempts against ID parameters.
• PoC indicators tied to public advisories or tooling.

Mitigation and prioritisation

• Apply vendor patch or upgrade to a secured version; if unavailable, implement compensating controls.
• Enforce parameterised queries/prepared statements and rigorous input validation on the affected parameter.
• Deploy WAF/IPS rules to block SQL injection attempts against the endpoint; restrict direct access to edit_customer.php.
• Harden server and database permissions; rotate credentials and monitor for anomalous activity.
• Change-management: implement an emergency remediation window; monitor KEV/EPSS updates and elevate to priority 1 if exploitation indicators become confirmed.
