It looks like you are working with an older or custom-built PHP blog system and are looking to improve your URL structure or SEO. The search operator inurl:index.php?id= typically targets dynamic pages that haven't been optimized for search engines.
Impact: Full database compromise, admin access.
If a site found via this dork is indeed vulnerable, the risks are severe:
That would find URLs containing "commy" in the URL, plus "index.php?id=".
Avoid relying on index.php?id-style URLs and on query-driven tactics that aim to exploit search operators like inurl:. Clean URLs, canonicalization, and quality content lead to better rankings, higher trust, and a smaller attack surface.
The primary reason someone looks for "better" versions of this dork is to find low-hanging fruit. If a developer has not properly "sanitized" the input for the id parameter, an attacker can append SQL commands to the URL to manipulate the database.
