$id = $_GET['id']; $result = mysql_query("SELECT * FROM guestbook WHERE id = $id"); Because "1" appears in the page, attackers test ?id=1' UNION SELECT ... phprar might indicate a parameter like ?lang=phprar that includes remote files:
It’s important to clarify upfront: Instead, this appears to be a Google dork — a specialized search operator used to find vulnerable, misconfigured, or outdated web applications.

“Old code is not legacy code – it’s vulnerable code until proven otherwise.”

Example vulnerable code:
| Component | Meaning | |-----------|---------| | intitle:"liveapplet" | The page title must contain the word “liveapplet” — likely an older applet-based chat or support tool. | | inurl:"lvappl" | The URL contains “lvappl” — possibly a directory or script prefix. | | "1" | The number 1 appears on the page — often used to find default or test data. | | guestbook | A guestbook script is present — traditionally vulnerable to XSS and SQL injection. | | phprar | Likely a typo or obscure reference to PHP remote file inclusion or a miswritten php.rar backup. | | top | Could indicate a “top” menu, ranking, or a leftover debug artifact. | | | inurl:"lvappl" | The URL contains “lvappl”
This article will break down what this dork means, why attackers use it, what risks it exposes, and how developers and server administrators can protect their systems. Let’s parse the operator step by step.
