XXE Vulnerability Scanner

Crashtest Security Suite is a scanner tool that checks for the OWASP Top 10 vulnerabilities, including XXE.
Find attack vectors in web applications.

  • Automated online SaaS XXE vulnerability scanner
  • XXE for File Retrieval
  • Data out-of-band exfiltration
  • Data Retrieval via Error Messages
  • XInclude Attacks


XXE vulnerability scanner features

The XXE scanner probes for XML External Entity vulnerabilities by executing security checks in your online application.

Our tool is designed to act as automated pentest software, DAST, which means we test in the same way a human cybersecurity expert would.

However, the findings may be quicker and less expensive than manual pentesting in this scenario.

XXE vulnerability scanner benefits

  • Share security reports in PDF, XML/JSON, or CSV formats with your team members.
  • Test for other vulnerabilities, like those in OWASP Top 10 2021 list.
  • Reduce the possibilities of data losses and safeguard your clients from the significant growth in cyber attacks in recent years.
  • The security of third-party components might be examined and rated.
  • Run automated XSS Scanner test on HTML-based web apps and JavaScript, AJAX, HTML5, Multi-Page and Single-Page Applications, and APIs.
  • Integrate easily into your workflow and dev pipeline.


Ample XML External Entity (XXE) report

The sophisticated XXE report provides in-depth information about your security state.

Check out how to fix what’s broken and save hours of manual testing and, as a result, money on cyber security.

Categorized vulnerability severity

The report begins with a broad summary of the vulnerabilities found in your scan target – the risks severity and their consequences. You’ll discover a list of every XML External Entity attack vector that was used, as well as other security information.

Tips for remediation

Each detected vulnerability includes a risk categorization, explanation, and extensive suggestions on how to resolve the issue.

Continuous Security

Cybersecurity Risk Reduction

Benchmark your next release against OWASP Top 10 and other known vulnerabilities.

Schedule Scans

Match vulnerability scanning to your agile dev cycle.

Ensure Compliance

Scan every new release before deployment and ensure compliance with regulations and standards (HIPAA, GDPR, ISO, and many more).

Faster Vulnerability Detection

Detect and mitigate vulnerabilities quicker by scanning your web assets regularly.

Integrated Dev Pipeline

Integrate vulnerability scanning into your dev process and environment and shift security left.



What are XXE Attacks?

Untrusted external references inside an XML file are evaluated by XML processors in some web applications. These references allow attackers to leverage external parameter entities to reveal information from configuration files, which they may use to compromise the system further.

Because these attacks are carried out by parsing XML inputs in a program, attackers can use them to gain access to other connected systems, resulting in application downtime and data loss. As a result, it is critical to comprehend the nature of these attacks and how they might be avoided.

What are XML External Entities?

XML external entities have values that are loaded outside of the Document Type Declaration (DTD).

Hackers can intercept data traveling to the server and inject harmful payloads if the parser that analyzes external entities is poorly configured.

What are the best practices to prevent XXE vulnerabilities?

While disabling the resolution of external entities is never enough, there are several ways to thwart XXE assaults successfully. Techniques that businesses may use to protect themselves from attacks involving External XML Entities:

  • Use simple data formats
  • Use updated XML processes and libraries
  • Disable Document Type Definition and XXE in all XML parsers
  • Use whitelisting for Server-Side Input Validation
  • Use SAST tools to identify XXE attack surfaces in source code

How potentially dangerous are XML external entities?

According to OWASP and the Common Weakness Enumeration (CWE) database, XXE attacks are among the top security concerns since they result in request forgery, denial of service, and the leaking of sensitive data. Because it may be carried out through various attack routes and is still regarded as a novel attack technique due to a lack of awareness among security teams, XXE attacks are widespread.
