Web Technologies Detection

When a host serves a web page on any HTTP port, QROS identifies the web technology stack running on that host — the server (nginx, Apache, LiteSpeed), the framework (Next.js, Express, Django, Laravel), the CMS (WordPress, Drupal, Magento, Joomla), and the JavaScript libraries (React, Vue, jQuery, Bootstrap). Each technology is matched against its known CVEs.

How QROS identifies web technologies

QROS uses a Wappalyzer-based detection engine that analyzes HTTP response headers, HTML meta tags, and page content to identify the web technology stack. For each detected technology, QROS reports:

• The technology name and category (CMS, framework, web server, JS library, analytics, CDN)
• The detected version (when available — extracted from headers, meta tags, or page content)
• The CVEs associated with that specific version
• The confidence level of the detection

Search by web technology

QROS lets you search the indexed host database by web technology — all WordPress sites, all nginx servers, all Apache servers, all Next.js sites — and see their CVEs. Find every WordPress 6.2 with known vulnerabilities, every Magento with critical CVEs, every outdated jQuery in seconds.

Why web technology detection matters

Attackers scan the internet for specific vulnerable web technologies. When a new WordPress plugin CVE is disclosed, they scan for every WordPress site running that plugin. QROS gives you the same visibility — you can find which of your hosts run vulnerable web technologies before attackers do.

What web tech detection looks like in QROS

When QROS detects a web technology stack on a host, it shows each technology as a badge with its version and CVE count:
