Enterprise-grade Automation with Pentester-level Flexibility

This library showcases real examples of how security teams use S4E Create with AI to save time, reduce manual effort, and strengthen their defenses.

Unlike traditional scanners that limit users to predefined checks, S4E Create with AI gives complete flexibility. You describe what you need, and the AI builds and runs it instantly. This allows teams to automate the exact tests they want instead of being restricted to what the product designer imagined.

Detecting Unexpected Access on Restricted Endpoints

Problem

Access control issues are among the most common and dangerous web vulnerabilities. Endpoints that should be restricted sometimes respond with success codes instead of expected 403 errors due to configuration errors or inconsistent policy enforcement.
Such small oversights can expose sensitive systems, administrative panels, or data sources that attackers can discover easily.

Risk Prevented: Unauthorized access and privilege escalation caused by missing or weak access control policies.

Traditional Approach

Security engineers often test restricted endpoints manually or rely on static vulnerability scanners that may miss context-based access rules. They send HTTP requests and review the responses one by one a time-consuming and error-prone process, especially across large environments with dozens of endpoints and access conditions.

How Create with AI Changes It

With S4E Create with AI, this validation can be automated across all verified assets in seconds. You define the behavior you expect (for example, “this endpoint should return 403”) and the AI builds a scan that sends an HTTP request and flags any unexpected response. It then reports evidence of unauthorized access attempts, helping teams identify broken access control issues before attackers can.

Instant Solution (Create with AI)

Prompt: Create a scan that sends a single HTTP request to the target. Normally, the target returns a 403 response. The scan should raise an alert and report access if a response other than 403 is received. The code should send an HTTP request and check the response status code.

The AI-generated scan performs a quick, non-destructive test and immediately highlights endpoints where access control is misconfigured.

🎥 Watch the Scan in Action

The video demonstrates Create with AI generating a scan that checks restricted endpoints, sending a single HTTP request, and flagging any unexpected access responses.

Value

  • Quickly detects broken access control issues across all assets
  • Provides immediate visibility into unauthorized access risks
  • Simplifies complex validation logic into a single automated check

Enables continuous monitoring with no manual scripting

Closing Takeaway

Access control errors are often silent and overlooked until it’s too late. S4E Create with AI turns this essential but repetitive test into an automated validation that runs continuously and alerts your team before exposure becomes exploitation.

🧰 Check It Yourself

Check the sample scan below or watch the video for a live walkthrough.

class Job(Task):
    def run(self):
        asset = http_or_https(asset=self.asset, _headers=self.headers, session=self.session)
        
        self.output['detail'] = []
        self.output['compact'] = []
        self.output['video'] = [f"python3 unexpected_access_scan.py {asset}"]

        response = self.session.get(asset, headers=self.headers, timeout=10, verify=False)
        
        if response.status_code != 403:
            self.output['compact'].append("Alert: Unexpected access granted.")
            self.output['detail'].append(f"Access granted with status code {response.status_code}.")
            self.output['video'].append(f"Unexpected access granted with response code: {response.status_code}.")
        else:
            self.output['compact'].append("No unexpected access.")
            self.output['detail'].append("Received expected 403 status code.")
            self.output['video'].append(f"Access blocked, received status code: {response.status_code}.")

    def calculate_score(self):
        if 'Alert: Unexpected access granted.' in self.output['compact']:
            self.score = 7
        else:
            self.score = 0
