CVE-2025-12248
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA security vulnerability has been detected in CLTPHP 3.0. The affected element is an unknown function of the file /home/search.html. Such manipulation of the argument keyword leads to sql injection. The attack may be performed from remote. The exploit has been disclosed publicly and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in CLTPHP 3.0's /home/search.html file allows remote attackers to inject malicious SQL queries via the 'keyword' parameter. The application fails to properly sanitize user input before using it in database queries, enabling attackers to manipulate query logic, extract data, or potentially execute commands.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm CLTPHP installationLocate CLTPHP by checking for characteristic files such as index.php, config.php, or a /home/ directory in the web root. Common paths: /var/www/html/, /wwwroot/, or the web server document root.Affected if CLTPHP is present in the environment
-
Identify installed CLTPHP versionOpen the main index.php or a version/config file in the CLTPHP installation directory. Look for a version variable or release notes file that states the version number.Affected if The installed version is 3.0 or falls within the 3.x branch
-
Verify vulnerable file existsCheck for the presence of /home/search.html in the CLTPHP web root. This file handles the search functionality.Affected if The file /home/search.html exists and is accessible via the web server
-
Confirm search feature uses keyword parameterAccess the search functionality via browser or curl: /home/search.html?keyword=test or /index.php/home/search/index?keyword=test. Inspect the HTTP request and response.Affected if The search page accepts the 'keyword' parameter and returns results without immediate error
-
Check for SQL injection vulnerability in keyword parameterSubmit a test payload in the keyword parameter such as a single quote (') or a sleep-based payload (e.g., keyword=test' AND SLEEP(5)--). Observe database response time or error messages.Affected if The application returns a database error or exhibits delayed response indicating unsanitized input is used in SQL queries
If CLTPHP 3.0 is installed, the /home/search.html file exists, and the search feature processes the 'keyword' parameter without sanitization, the environment is affected by this SQL injection vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries or prepared statements to ensure the 'keyword' parameter is treated as literal data rather than executable code. Validate and sanitize all user inputs before database operations.
