Website Encountering “Perhaps Dangerous Request.Path Value,” Prompting Security Review
A website is currently experiencing errors due to a “Potentially Dangerous Request.Path Value” being detected from a client.This System.Web.HttpException indicates the web application has identified a potential security risk within the incoming web request’s path.
Technical Details of the Error
The error stems from the ASP.NET framework’s built-in request validation process. Specifically, the System.Web.HttpRequest.ValidateInputIfRequiredByConfig() function, called during the request pipeline, flags the Request.Path value as potentially harmful.
Stack trace Indicates Validation Failure
The stack trace confirms that the error originates during input validation:
[HttpException (0x80004005): 클라이언트 (?)에서 잠재적 위험이 있는 Request.Path 값을 발견했습니다.]
System.Web.HttpRequest.ValidateInputIfRequiredByConfig() +9941168
system.Web.PipelineStepManager.ValidateHelper(HttpContext context) +53
Potential Implications and Mitigation
This error usually suggests a potential Cross-Site Scripting (XSS) or similar injection attack attempt. The system is designed to prevent malicious code from being injected into the application through the URL.
Immediate review of recent code changes and user input handling is recommended. Consider implementing more robust input sanitization and validation techniques to prevent similar vulnerabilities. Reviewing the webserver’s security settings and ensuring the application is running on the latest secure versions of .NET framework are also crucial.
Surroundings Information
The website is running on Microsoft .NET Framework version 4.0.30319 and ASP.NET version 4.7.3930.0.

Q&A: Decoding the “potentially Dangerous Request.Path Value” Error
What does “Potentially Dangerous Request.Path Value” actually mean?
This error is ASP.NET’s way of saying, “Hey, somthing in the URL looks suspicious!” It’s like a digital security guard spotting a suspicious package. It flags parts of the URL,particularly the path portion (e.g., /path/to/resource), that might contain malicious code.
Why is this happening?
This error is triggered by the ASP.NET framework’s built-in request validation,designed to prevent attacks like Cross-Site Scripting (XSS) or SQL injection. Malicious actors try to inject harmful code through the URL, and this feature is designed to catch them.
What’s a “Request.Path?”
The Request.Path is the part of the URL that comes after the domain name. For exmaple, in “www.example.com/products/details,” “products/details” is the request path. Attackers often try to insert malicious code within this path.
What’s the stack trace, and why is it important?
The stack trace shows the sequence of events that led to the error. It helps developers pinpoint where the error originates. In this case, it points to the ValidateInputIfRequiredByConfig() function, confirming ASP.NET’s input validation is the culprit.
What are the potential risks?
The primary risk is that an attacker could inject malicious code into your website. This could lead to XSS attacks (where attackers can steal user data or deface the website) or other vulnerabilities.
How can this error be fixed?
The article suggests a review of recent code changes, especially those related to user input handling. Developers shoudl implement robust input sanitization and validation to ensure that all user-provided data is safe. Updating to the latest .NET framework version is also crucial.
Is the .NET Framework version a factor?
Yes. The article mentions the website uses .NET Framework 4.0. While older versions might be susceptible to vulnerabilities, it’s not always the main cause of this error. Input validation is a consistent part of the framework, but newer versions have updates that may offer better protection.
Can this happen on any website?
Yes, any website built using ASP.NET is potentially vulnerable. However,the risk can be greatly reduced by following best practices for input validation and security.
Engaging Trivia
Did you no that input validation is like the security guard at a concert venue? It checks IDs (user input) to prevent unauthorized access (malicious code) and keeps the event safe (website secure).
protecting your website from this ”Potentially Dangerous Request.Path Value” error is crucial. take the recommended steps to secure your site and keep your users safe.
