• → SQL injection via the `author` GET parameter in authors_post.php; monitor for inline comment obfuscation (/*!11111...*/) and UNION-based payloads in that parameter. ↗
• → Payload uses MySQL versioned inline comments (/*!11111UNION*/, /*!11111SELECT*/, /*!11111CONCAT_WS*/) to bypass WAF/filters; detect requests to authors_post.php containing `/*!` sequences in query parameters. ↗
• → Detect the classic SQL injection terminator `--+-` in HTTP query strings targeting authors_post.php, combined with hex-encoded values (0x...) indicative of UNION SELECT data exfiltration. ↗

• · The exploit PoC uses `localhost` as the target host; in real-world attacks the hostname will vary — detection rules should match on the path `/authors_post.php` and the `author` parameter pattern rather than the host. ↗
• · The `[PATH]` portion of the URL is variable and depends on the installation directory of Super Cms Blog Pro 1.0; detection signatures must account for arbitrary sub-paths before `authors_post.php`. ↗
