CVE Alert: CVE-2025-11477 – SourceCodester – Wedding Reservation Management System

Risk verdict

High risk: a publicly disclosed, unauthenticated remote SQL injection with a PoC available enables possible data leakage and alteration without user interaction.

Why this matters

The flaw permits remote access to the database via user-supplied input, potentially exposing personal or transactional data and enabling data manipulation. Business impact includes customer trust erosion, regulatory exposure, and possible downtime of the reservation system if the backend is disrupted.

Most likely attack path

Attacker requires no user credentials and can target the vulnerable web endpoint over the network (low attack complexity). The injection can read or modify data (C:L/I:L/A:L), with no privilege escalation implied, so initial access may suffice for partial data compromise; limited scope but potential for repeated exfiltration if not mitigated.

Who is most exposed

Public or poorly protected deployments of the web application, especially internet-facing instances hosted on shared or small-business environments, are at highest risk. Organisations that run outdated or unpatched installations with exposed database connections are especially vulnerable.

Detection ideas

• Alerts for anomalous SQL-like payloads to the affected endpoint.
• WAF logs showing SQLi patterns or evasion attempts.
• Unexpected error messages or abnormal query execution in app or DB logs.
• Unusual data access patterns or large data dumps from user-related tables.
• Signatures or indicators from public PoC tooling.

Mitigation and prioritisation

• Apply vendor patch or upgrade to patched version as a first step.
• If patching is not possible, implement a virtual patch/WAF rule to block SQLi payloads.
• Enforce input validation and parameterised queries; least-privilege DB accounts; disable verbose DB/app error output.
• Limit internet exposure of the application and segment the web tier from the database.
• Plan rapid testing and deployment in a controlled change window; monitor post-implementation for anomalies.
