CVE Alert: CVE-2025-12248 – n/a – CLTPHP

Risk verdict

High risk: remote, unauthenticated SQL injection with publicly disclosed exploit for CLTPHP 3.0; patch and monitor urgently.

Why this matters

An attacker can manipulate the keyword parameter from anywhere, potentially exfiltrating or altering data. Even with low individual impact per CVSS, the exposure of unauthorised database access can enable broader reconnaissance, data leakage, or disruption if paired with automated tooling.

Most likely attack path

No user interaction required; attacker sends crafted input via the search.html keyword, triggering SQL injection on the backend. No privileges are required, and the breach can occur over the public internet, with potential lateral movement limited to the database layer but capable of data exfiltration or modification.

Who is most exposed

Web sites running CLTPHP 3.0 with internet-facing search functionality, especially those on self-hosted or small hosting environments lacking timely patches or input sanitisation.

Detection ideas

• Log analysis showing unusual keyword payloads and SQL error messages in search responses
• WAF/IDS alerts for classic SQLi patterns in the search parameter
• Abnormal spikes in search requests or DB query latency
• Unexpected database errors returned to clients
• IOC streams indicating external probing of search.html

Mitigation and prioritisation

• Apply vendor patch or upgrade to a fixed CLTPHP release; verify integrity in a staging environment
• Enforce parameterised queries and input validation for the search keyword
• Disable detailed error messages and generic stack traces in production
• Implement WAF rules targeting SQLi patterns on the search endpoint
• Review access controls and DB permissions for the web app user; implement least privilege; plan a formal change-management window for the update
• Monitor broadly for exploitation attempts and validate patch effectiveness after deployment
