CVE Alert: CVE-2025-11348 – Campcodes – Online Apartment Visitor Management System

Risk verdict

Publicly disclosed SQL injection enables remote, unauthenticated access with a PoC exploit; treat as high urgency.

Why this matters

Attacker-controlled SQL can exfiltrate or alter data, compromising personal information and system integrity. The vulnerability is network-facing, requires no user interaction, and CVSS indicates high exploitability, increasing the likelihood of automated targeting.

Most likely attack path

An attacker supplies a crafted Username value via index.php to trigger the injection, gaining backend access without credentials. With low complexity and remote vector, successful exploitation can yield data or enable follow-on actions; escalation is possible if DB access is broad, but constrained by app and database permissions.

Who is most exposed

Any internet-facing deployment of the Campcodes system, especially in small-to-medium organisations using hosted or on-prem installations, is at risk.

Detection ideas

• Web server logs show anomalous SQL error messages or database failures from index.php
• Requests contain typical SQLi patterns in Username (e.g., tautologies, union/select payloads)
• Sudden spikes in 500 responses or unusual DB query errors
• Unusual or repetitive requests from unknown IPs targeting the login/visitor endpoints
• WAF/IDS alerts for SQL injection signatures or payloads

Mitigation and prioritisation

• Apply vendor patch or upgrade to the fixed version as soon as available
• Enforce parameterised queries, strict input validation, and avoid direct SQL string concatenation
• Run with least-privilege DB credentials; restrict user rights to necessary operations
• Deploy targeted WAF/IDS rules to block common SQLi patterns and monitor for PoC indicators
• Validate changes in a test/Staging environment; implement a rollback plan and change-management approvals
• Enable continuous monitoring for data exfiltration and anomalous DB activity
