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
Multiple PHP remote file inclusion vulnerabilities in mcGuestbook 1.3 allow remote attackers to execute arbitrary PHP code via a URL in the lang parameter to (1) admin.php, (2) ecrire.php, and (3) lire.php. NOTE: it was later reported that the ecrire.php vector also affects 1.2. NOTE: this issue might be limited to a race condition during installation or an improper installation, since a completed installation creates an include file that prevents external control of the $lang variable.

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

Remote File Inclusion (RFI) vulnerability in mcGuestbook 1.3 allows remote attackers to execute arbitrary PHP code by supplying a URL in the 'lang' parameter to admin.php, ecrire.php, or lire.php. The vulnerability stems from unsanitized user input being passed to PHP's include() or require() functions, enabling inclusion of malicious remote files.

MitigationComplete the installation properly as instructed (this creates a protective include file that prevents external control of the $lang variable), or upgrade to a patched version of mcGuestbook if available.

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. Confirm mcGuestbook installation
    Locate the mcGuestbook installation directory on the web server and identify the version number, typically found in a README, VERSION file, or the main index/config file
    Affected if The installed version is mcGuestbook 1.3
  2. Verify vulnerable script presence
    Check if admin.php, ecrire.php, or lire.php exist in the mcGuestbook web directory
    Affected if Any of these three PHP files are present in the installation
  3. Inspect lang parameter handling
    Open admin.php, ecrire.php, or lire.php in a text editor and search for code that uses the 'lang' parameter with include() or require() without validation
    Affected if Code passes the lang parameter directly to include() or require() without sanitization
  4. Check for protective include file
    Look for a configuration or include file within mcGuestbook that is supposed to be created during installation (refer to installation documentation for expected filename) and verify it exists and restricts $lang
    Affected if The protective file does not exist or does not properly restrict the $lang variable

A user is affected if mcGuestbook 1.3 is installed, the vulnerable PHP files exist, and the lang parameter is passed unsanitized to include/require without a protective include file present.
