Summary of Vulnerabilities in HTTP/HTTPS Protocols: How to Check and Prevent Them

The following is a classification and organization of vulnerabilities in the HTTP/HTTPS protocols based on the perspectives of black box testingwhite box testing and gray box testing:

1. Black Box Testing (External Perspective, No Internal Access)

Definition: Simulates the attacker’s perspective, testing only through external network interfaces without relying on internal system code or configuration information.

Check Content and Tools:

Vulnerability Type Testing Method
Plaintext Transmission Check if the URL is <span>HTTPS</span> (indicated in the browser address bar), use <span>nmap</span> to scan ports (80/443).
Man-in-the-Middle Attack Risk Verify certificate validity (browser warnings, <span>openssl s_client -connect</span>), check for support of weak protocols (SSLv3/TLS 1.0).
Weak Encryption Algorithms Use external tools for scanning (e.g., Qualys SSL Labs, <span>testssl.sh</span>).
Mixed Content Check the browser console for <span>Mixed Content</span> warnings.
Missing HSTS Check if the response header contains <span>Strict-Transport-Security</span>.
Clickjacking Check if <span>X-Frame-Options</span> or <span>Content-Security-Policy</span> headers are missing.
Certificate Issues Verify if the certificate is expired, and if it is issued by a trusted CA (e.g., browser prompts, <span>certbot</span> checks).
Protocol Downgrade Attack Force the client to use a lower version of the protocol (e.g., TLS 1.0) and observe if it succeeds.

Tools:

  • Scanning Tools: Nmap, Wireshark, Burp Suite, ZAP

  • Online Services: Qualys SSL Labs, Security Headers

  • Command Line Tools: cURL, OpenSSL

Usage examples:

Below is a detailed usage method and common scenario examples for <span>openssl s_client -connect</span>:

Basic Syntax

openssl s_client -connect <host>:<port> [options]
  • <span><host></span>: Target server domain name or IP.

  • <span><port></span>: Target port (e.g., HTTPS default 443).

Common Options and Examples

1. Basic Connection Test

Check if the server SSL/TLS handshake is successful:

openssl s_client -connect www.example.com:443

Output Focus Points:

  • Certificate Chain (<span>Certificate chain</span>)

  • Protocol Version (<span>Protocol</span>)

  • Cipher Suite (<span>Cipher</span>)

  • Certificate Verification Result (<span>Verify return code</span>).

2. Display Full Certificate Chain

Use <span>-showcerts</span> to display all certificates returned by the server:

openssl s_client -connect www.example.com:443 -showcerts

Purpose: Check if intermediate certificates are missing.

3. Specify Protocol Version

Test if the server supports a specific TLS version:

  • TLS 1.2:

openssl s_client -connect www.example.com:443 -tls1_2
  • TLS 1.3:

openssl s_client -connect www.example.com:443 -tls1_3

Purpose: Verify if old protocols (e.g., SSLv3, TLS 1.0/1.1) have been disabled.

4. Check Cipher Suite

Test if the server supports a specific cipher suite:

openssl s_client -connect www.example.com:443 -cipher 'ECDHE-RSA-AES128-GCM-SHA256'

Purpose: Verify if weak cipher suites (e.g., RC4, DES) have been disabled.

5. Verify Certificate Status

Enable OCSP stapling check:

openssl s_client -connect www.example.com:443 -status

Output Focus Points:

  • If it shows <span>OCSP Response Status: successful</span>, it indicates that the server has enabled OCSP stapling.

6. Debug Handshake Process

Display detailed protocol interaction information:

openssl s_client -connect www.example.com:443 -msg

Purpose: Diagnose reasons for handshake failures (e.g., protocol or suite mismatches).

7. Specify CA Certificate

Use a custom CA certificate to verify the server certificate:

openssl s_client -connect internal.example.com:443 -CAfile /path/to/custom-ca.crt

Purpose: Test self-signed certificates or certificates issued by private CAs.

8. Test STARTTLS

Check services that support STARTTLS (e.g., SMTP, IMAP):

openssl s_client -connect smtp.example.com:587 -starttls smtp

Supported Protocols: <span>smtp</span>, <span>pop3</span>, <span>imap</span>, <span>ftp</span>, <span>xmpp</span>, etc.

9. Save Output to File

Save complete handshake information for later analysis:

openssl s_client -connect www.example.com:443 > ssl_output.txt 2>&1

Common Issue Diagnosis

1. Certificate Verification Failed (<span>Verify return code: 20</span>)

  • Reason: Incomplete certificate chain or root certificate not trusted.

  • Solution:

    • Use <span>-showcerts</span> to check for missing intermediate certificates.

    • Update the system’s CA certificate bundle (e.g., <span>/etc/ssl/certs/ca-certificates.crt</span>).

2. Handshake Failed (<span>SSL handshake failed</span>)

  • Reason: Protocol/suite incompatibility.

  • Solution:

    • Specify protocol version (e.g., <span>-tls1_2</span>).

    • Check the supported cipher suites on the server (e.g., <span>nmap --script ssl-enum-ciphers</span>).

3. OCSP Stapling Not Enabled

  • Phenomenon: <span>OCSP response: no response sent</span>.

  • Solution: Enable OCSP stapling in the server configuration.

Summary

<span>openssl s_client</span> is a powerful tool for diagnosing SSL/TLS connection issues, allowing for quick verification of:

  • Certificate validity

  • Protocol and cipher suite configuration

  • OCSP stapling status

  • STARTTLS support

Combined with tools like <span>Qualys SSL Labs</span> or <span>testssl.sh</span>, it can provide a more comprehensive assessment of server security.

  • Conclusion: SSLv2/3 and TLS 1.0/1.1 have been disabled, meeting security standards.

2. Cipher Suite Detection

Hexcode  Cipher Suite Name (IANA/RFC)                        KeyExch.  Encryption  Bits     Cipher Suite Name (OpenSSL)
-------------------------------------------------------------------------------------------------------------------------
x1302   TLS_AES_256_GCM_SHA384                             ECDH 253   AESGCM      256      TLS_AES_256_GCM_SHA384         
x1303   TLS_CHACHA20_POLY1305_SHA256                       ECDH 253   ChaCha20    256      TLS_CHACHA20_POLY1305_SHA256   
x1301   TLS_AES_128_GCM_SHA256                             ECDH 253   AESGCM      128      TLS_AES_128_GCM_SHA256         
  • Conclusion: Only strong cipher suites (AES-GCM, ChaCha20) supported for TLS 1.3.

3. Certificate Issues

Certificate Validity (UTC)     >=60d (Warn) <=825d (ok)   expires in 825d (2025-01-15 23:59:59)
  • Risk: Certificate validity period is too long (over 825 days), recommended to shorten to within 1 year.

6. Remediation Suggestions

1. Protocol and Suite Issues

  • Disable Weak Protocols: If SSLv3/TLS 1.0 is detected, configure the server to enable only TLS 1.2+.

  • Optimize Cipher Suites: Prefer forward secrecy suites (e.g., <span>ECDHE-ECDSA-AES256-GCM-SHA384</span>).

2. Certificate Management

  • Shorten Validity Period: Use Let’s Encrypt for automatic renewal (90 days validity).

  • Enable OCSP Stapling: Reduce certificate revocation check delays.

3. Security Hardening

  • Configure HSTS: Add <span>Strict-Transport-Security</span> response header.

  • Enable HTTP/2: Improve performance through ALPN negotiation.

7. Notes

  1. Permission Issues:

  • Directly scanning port 443 may require <span>sudo</span> (not mandatory).

  • False Positive Handling:

    • If vulnerabilities are falsely reported (e.g., false positive for Heartbleed), check if the server’s OpenSSL version has been patched.

  • Performance Impact:

    • Comprehensive scans may take a long time; it is recommended to perform them during off-peak hours in production environments.

    With <span>testssl.sh</span>, you can quickly locate TLS/SSL configuration vulnerabilities, and combined with remediation suggestions, significantly enhance server security. Regular scans (e.g., monthly) and keeping the tool updated (<span>git pull</span>) are recommended.

    2. White Box Testing (Internal Perspective, Code/Configuration Access)

    Definition: Analyze potential vulnerabilities based on internal code, configuration files, and logs, requiring system administrator or developer permissions.

    Check Content and Tools:

    Vulnerability Type Testing Method
    Weak Encryption Algorithms Check server configuration files (e.g., Nginx/Apache’s <span>ssl_ciphers</span>), disable weak cipher suites.
    Session Cookie Security Code audit: Check if cookies are set with <span>Secure</span>, <span>HttpOnly</span>, and <span>SameSite</span> attributes.
    Certificate Management Verify the storage location and permission settings of the certificate private key (e.g., whether the private key is accidentally exposed).
    HSTS Configuration Check if the server is configured with <span>Strict-Transport-Security</span> header and its parameters (<span>max-age</span>, <span>preload</span>).
    Missing Security Headers Check in code or configuration files for <span>Content-Security-Policy</span>, <span>X-XSS-Protection</span>, and other response headers.
    Mixed Content Issues Code audit: Check if static resource links enforce HTTPS.
    Log Leakage of Sensitive Information Analyze log files for sensitive data (e.g., passwords, cookies).

    Tools:

    • Configuration Check: SSH login to the server to view Nginx/Apache configuration

    • Code Audit: IDE search for keywords (e.g., <span>setCookie</span>), Git repository scanning

    • Automation Tools: TruffleHog (detect key leaks), Bandit (Python code audit)

    3. Gray Box Testing (Mixed Perspective, Partial Internal Information)

    Definition: Combine partial internal information (e.g., logs, configuration snippets), but do not fully rely on code or administrator permissions.

    Check Content and Tools:

    Vulnerability Type Testing Method
    Man-in-the-Middle Attack Risk Analyze logs for abnormal connections (e.g., numerous TLS handshake failure records).
    Protocol Downgrade Attack Verify if old protocols are disabled using partial configuration information (e.g., check supported TLS versions on the server).
    Certificate Revocation Status Use <span>openssl</span> to check if OCSP Stapling is enabled (requires partial server configuration permissions).
    Mixed Content Issues Verify resource loading policies through partial code snippets or build tool configurations.
    Clickjacking Analyze risks of frame embedding using partial response header information (e.g., <span>X-Frame-Options</span>) and page content.
    HSTS Preload Verify if the domain has been submitted to the HSTS Preload List.

    Tools:

    • Log Analysis: ELK Stack (Elasticsearch, Logstash, Kibana), Splunk

    • Configuration Snippet Analysis: Ansible/Puppet configuration file snippets

    • Mixed Tools: Postman (custom request header testing), browser developer tools (network panel analysis)

    4. Summary and Scenario Recommendations

    1. Black Box Testing:

    • Applicable Scenarios: Penetration testing, external security assessments.

    • Goal: Simulate real attacker behavior to discover exposed vulnerabilities.

  • White Box Testing:

    • Applicable Scenarios: Code audits, internal security hardening.

    • Goal: Fix configuration errors or code defects from the root.

  • Gray Box Testing:
