This forces Apache to only report "Apache" without revealing the exact, potentially vulnerable version number during automated scans. Conclusion
The attacker uses mass-scanning tools (e.g., masscan or zmap ) to find active hosts responding on port 2222.
The script simply reads the inner HTML of the response, extracts the genuine session cookie, and sends it to the attacker. Remediation and Mitigation Strategies
Extract the HttpOnly session tokens and exfiltrate them to an attacker-controlled server. Anatomy of the Apache 2.2.22 Exploit apache httpd 2222 exploit
: Echo sends a request to the server with a header so long or malformed that the server simply can't process it. Instead of a normal page, the server triggers a "Bad Request" (400 Error)
One of the most common payloads delivered after an alleged "Port 2222 exploit" is the (also known as Kaiten). Let us examine why it uses port 2222.
: Execute netstat -tulpn | grep 2222 on Linux to determine exactly which software binary is currently bound to that port. This forces Apache to only report "Apache" without
The HttpOnly flag is a security measure applied to cookies. It instructs the browser that the cookie should not be accessible via client-side scripts (such as JavaScript's document.cookie ). This flag is the primary defense against session hijacking via traditional Cross-Site Scripting (XSS) attacks. How the Exploit Bypasses It
Beyond the "double 2" family, several other critical vulnerabilities have threatened Apache HTTP Server configurations. The following table details some of the most severe ones:
Moving Apache to port 2222 does not inherently secure it. Any known CVE (Common Vulnerabilities and Exposures) affecting your specific version of Apache HTTPd will still be fully exploitable on port 2222. 3. SSH Honeypots and Port Shifting Let us examine why it uses port 2222
When a vulnerability scanner or a manual penetration test flags an asset as running "Apache HTTP Server Prior to 2.2.22"
