Introduction
Pentesting has long been a cornerstone of cybersecurity, designed to uncover vulnerabilities through expert analysis. However, many reports today are reduced to automated tool outputs with little critical thinking, leading to irrelevant or misleading findings. This article explores the pitfalls of low-effort pentesting and how to distinguish real security assessments from checkbox exercises.
Learning Objectives
- Understand why automated pentesting reports often fail to address real risks
- Learn how to evaluate pentesting vendors for quality and expertise
- Discover key manual techniques that separate skilled testers from script runners
You Should Know
1. The Problem with Automated TLS 1.2 “Findings”
Many automated scanners flag TLS 1.2 as a vulnerability, despite its widespread secure use. A proper pentest should assess cipher suites and configuration rather than blindly recommending deprecation.
Example OpenSSL Command to Check Ciphers:
openssl ciphers -v 'TLSv1.2' | awk '{print $1}' | sort -u
Steps:
- Run this command on your server to list supported ciphers.
- Verify if weak ciphers (e.g.,
CBC-based) are present. - Disable weak ciphers in your web server config (e.g., Apache/NGINX).
-
Why Client-Side Password Encryption Is a Red Flag
Some reports suggest encrypting passwords on the client side before transmission—a misleading “fix” that ignores real threats like MITM attacks.
Example of Proper HTTPS Enforcement (Apache):
<VirtualHost :443> SSLEngine on SSLProtocol all -SSLv3 -TLSv1 -TLSv1.1 SSLCipherSuite HIGH:!aNULL:!MD5 </VirtualHost>
Steps:
1. Ensure TLS 1.2+ is enforced.
2. Disable outdated protocols (SSLv3, TLS 1.0/1.1).
3. Use HSTS to prevent downgrade attacks.
3. Detecting and Mitigating Pre-Login CSRF
A pre-login CSRF finding often indicates a poorly scoped test rather than a real threat.
Testing for CSRF with cURL:
curl -X POST http://example.com/login -H "Content-Type: application/json" -d '{"user":"test","pass":"test"}' --cookie "session=123"
Steps:
1. Check if the endpoint lacks CSRF tokens.
- Verify if state-changing actions (e.g., login) are vulnerable.
3. Implement anti-CSRF tokens or SameSite cookies.
4. How to Evaluate a Pentest Vendor
A quality pentest should include manual exploitation, chaining vulnerabilities, and business logic flaws.
Questions to Ask Vendors:
- Do you perform manual exploitation beyond automated scans?
- Can you provide examples of chained vulnerabilities from past reports?
- How do you prioritize findings based on actual risk?
5. Manual Techniques Skilled Pentesters Use
Example: Manual SQLi Testing with Time-Based Delays
SELECT IF(1=1, SLEEP(5), 0);
Steps:
1. Test inputs with time-delay payloads.
2. Observe response times to confirm blind SQLi.
3. Escalate to data exfiltration if vulnerable.
What Undercode Say
- Key Takeaway 1: Automated tools alone don’t replace human expertise—vendors must demonstrate manual testing.
- Key Takeaway 2: Findings like “disable TLS 1.2” or “client-side encryption” often indicate low-value assessments.
Analysis:
The rise of compliance-driven pentesting has led to checkbox-style reports that prioritize quantity over quality. Skilled testers focus on real-world attack scenarios, not just scanner output. Companies must demand better by selecting vendors with proven manual testing methodologies.
Prediction
As AI-driven scanning improves, low-quality pentesting may worsen, flooding reports with false positives. However, organizations that invest in expert-led assessments will gain a true security advantage, reducing breach risks significantly.
