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 · unedited
A remote code execution (RCE) vulnerability exists in the Pi Camera project, version 1.0, maintained by RECANTHA. The issue arises from improper sanitization of user input passed to the "position" GET parameter in the tilt.php script. An attacker can exploit this by sending crafted input data that includes malicious command sequences, allowing arbitrary commands to be executed on the server with the privileges of the web server user. This vulnerability is exploitable remotely and poses significant risk if the application is exposed to untrusted networks.

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 confidence

A command injection vulnerability exists in the tilt.php script of the Pi Camera project v1.0 where the 'position' GET parameter is not sanitized before being used in a system call. Attackers can inject arbitrary OS commands through crafted input to the parameter, achieving RCE with web server user privileges.

MitigationImplement strict input validation on the 'position' parameter using allowlists or type checking, and refactor code to avoid passing user input to shell execution functions; if shell commands are required, use parameterized APIs or explicit whitelisted values.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate tilt.php script
    Search the web server's document root for the file named tilt.php (e.g., find /var/www -name tilt.php 2>/dev/null or locate tilt.php)
    Affected if The script exists and is part of a Pi Camera installation
  2. Verify Pi Camera version
    Check for a version file or examine the tilt.php header/comment for version v1.0; compare against the affected version range
    Affected if The installed version is Pi Camera v1.0
  3. Inspect position parameter handling
    Open tilt.php and search for usage of $_GET['position'] or $_REQUEST['position']; verify if the value is passed directly to shell functions like exec(), shell_exec(), system(), passthru(), or backtick operators without sanitization
    Affected if The code passes the 'position' parameter to a shell execution function without input validation or escaping
  4. Confirm web accessibility
    Verify the script is accessible via HTTP/HTTPS on the web server (e.g., test accessing tilt.php?position=test via curl or browser)
    Affected if The script is web-facing and the vulnerable parameter can be supplied via URL

You are affected if the tilt.php script exists in your Pi Camera v1.0 installation and it passes the 'position' GET parameter directly to shell execution functions without sanitization.
