Two Overlooked Security Issues Attackers Frequently Abuse

When organizations think about web application security, they often focus on vulnerabilities like SQL Injection, XSS, or authentication flaws.

However, many successful attacks begin much earlier.

Sometimes the attacker simply discovers an exposed administrative interface. Other times, they find dangerous HTTP methods enabled on the server and use them to access functionality that should never be publicly available.

In today's blog, we'll explore two important OWASP WSTG configuration testing areas:

  • Enumerating Infrastructure and Application Admin Interfaces (WSTG-CONF-05)
  • Testing HTTP Methods (WSTG-CONF-06)

Together, these tests help identify hidden functionality and server misconfigurations before attackers do.

Why These Issues Matter

Every web application contains functionality that regular users should never access.

Examples include:

  • Administrative dashboards
  • User management portals
  • Configuration panels
  • Internal APIs
  • Maintenance interfaces

Similarly, web servers often support additional HTTP methods beyond GET and POST. If these methods are improperly configured, attackers may gain access to dangerous functionality.

A single exposed admin panel combined with weak server configuration can sometimes result in a complete application compromise.

Enumerating Admin Interfaces

What Are Admin Interfaces?

Admin interfaces are areas of an application used by privileged users to manage systems and data.

Typical administrative functions include:

  • Creating users
  • Managing permissions
  • Updating application settings
  • Viewing sensitive information
  • Managing infrastructure

Common URLs include:

/admin
/administrator
/manage
/dashboard
/controlpanel
/backend

These pages are often hidden from public navigation but remain accessible if someone knows the URL.

OWASP recommends identifying hidden administrator functionality and determining whether unauthorized users can access it.

How Attackers Find Admin Panels

Directory Enumeration

One of the most common techniques is brute-forcing directories.

ffuf -u https://target.com/FUZZ -w common.txt
dirsearch -u https://target.com

This frequently reveals hidden paths such as:

/admin
/admin/login
/manage
/console
/internal

Reviewing Source Code

Developers sometimes accidentally expose administrative paths inside:

  • HTML comments
  • JavaScript files
  • API references

Example:

<!-- Internal Admin Portal: /internal-admin -->

What appears to be a harmless comment can expose sensitive functionality.

Search Engine Discovery

Sometimes admin pages become indexed by search engines.

Examples:

site:target.com inurl:admin
site:target.com intitle:"Admin Login"

This simple technique has revealed countless exposed administration panels over the years.

Common Findings

Missing Authentication

An admin panel is accessible without logging in.

https://target.com/admin

This should immediately be considered critical.

Weak Authentication

Default credentials remain surprisingly common.

admin:admin
administrator:password

Attackers actively test these combinations.

Broken Authorization

Sometimes normal users can directly access administrator pages.

Example:

/user/profile

changed to:

/admin/users

If access is granted, the application suffers from privilege escalation.

Real-World Example

Imagine an e-commerce platform.

Customers can:

  • View products
  • Place orders
  • Manage profiles

Administrators can:

  • Create products
  • Refund orders
  • Modify prices
  • Manage user accounts

If an exposed admin panel lacks proper authorization controls, an attacker could take complete control of the business operations.

Dangerous HTTP Methods

Understanding HTTP Methods

Every request sent to a web server contains an HTTP method.

Most applications use:

GET
POST

However, servers often support additional methods:

PUT
DELETE
TRACE
OPTIONS
PATCH
CONNECT

If these methods are enabled unnecessarily, they can introduce serious security risks.

OWASP specifically recommends testing unusual HTTP methods because they may expose unintended functionality.

Discovering Allowed Methods

A tester can identify supported methods using:

curl -X OPTIONS https://target.com -I

Example response:

Allow: GET, POST, PUT, DELETE

This tells us exactly what the server accepts.

Dangerous Method #1 — PUT

PUT allows resources to be uploaded or replaced.

Example:

PUT /test.txt

Misconfigured servers may allow attackers to upload files directly.

Potential impacts include:

  • Website defacement
  • Malware hosting
  • Remote code execution

Dangerous Method #2 — DELETE

DELETE removes resources.

Example:

DELETE /backup.zip

Improper authorization checks may allow attackers to delete application data.

Dangerous Method #3 — TRACE

TRACE is primarily intended for debugging.

The server reflects the request back to the client.

OWASP notes that TRACE can sometimes be abused during Cross-Site Tracing (XST) attacks to expose sensitive information.

Example:

TRACE /

Best practice is usually to disable TRACE unless absolutely required.

HTTP Method Override Abuse

Modern frameworks sometimes support HTTP method overriding.

Common headers include:

X-HTTP-Method
X-HTTP-Method-Override
X-Method-Override

OWASP highlights that these headers may allow restricted methods to be processed even when the server appears to block them.

Example:

POST /resource
X-HTTP-Method-Override: DELETE

Although the request appears to be a POST, the application may process it as a DELETE operation.

Real-World Scenario

Consider a document management application.

Administrators disable DELETE requests at the web server level.

However, the backend framework still accepts:

X-HTTP-Method-Override: DELETE

An attacker discovers this behavior and deletes sensitive documents despite the apparent restriction.

The application appears secure from the outside but remains vulnerable because of a hidden configuration issue.

How These Issues Work Together

Imagine the following attack chain:

Step 1

Attacker discovers:

/admin

through directory enumeration.

Step 2

Authorization checks are weak.

The attacker gains limited administrative access.

Step 3

The server supports:

PUT
DELETE

or method overriding.

Step 4

The attacker uploads malicious files, modifies content, or deletes application resources.

What started as a simple hidden URL discovery quickly becomes a full compromise.

Security Recommendations

To protect applications:

For Admin Interfaces

  • Remove unused admin portals
  • Restrict access through VPNs
  • Implement MFA
  • Enforce strong passwords
  • Conduct regular access reviews
  • Monitor administrative activity

For HTTP Methods

  • Allow only required methods
  • Disable TRACE
  • Restrict PUT and DELETE
  • Disable unnecessary method override features
  • Validate authorization on every request
  • Monitor suspicious HTTP activity

Final Thoughts

Security issues aren't always hidden deep inside application code.

Sometimes they are sitting in plain sight:

  • An exposed admin panel nobody noticed
  • A forgotten administrative endpoint
  • A dangerous HTTP method left enabled by default

Attackers actively search for these weaknesses because they are often easier to exploit than complex vulnerabilities.

As security testers, identifying these overlooked attack surfaces can prevent a small configuration mistake from becoming a major security incident.
