NOC WAF Protects Against

Remote Code Execution (RCE)

Remote code execution (RCE) attacks allow an attacker to remotely execute malicious code. RCE vulnerabilities are the worst of the worst when it comes to software vulnerabilities for your web application.

Understanding RCE Vulnerabilities

RCE Injections

RCE vulnerabilities are considered to be the worst of the worst when it comes to software vulnerabilities. At OWASP, they are thrown into the Code Injection bucket.

 

Code Injection is the general term for attack types which consist of injecting code that is then interpreted/executed by the application. This type of attack exploits poor handling of untrusted data. These types of attacks are usually made possible due to a lack of proper input/output data validation, for example:

 

  • allowed characters (standard regular expressions classes or custom)
  • data format
  • amount of expected data

RCE Risk Factors

Command injection attacks are possible when an application passes unsafe user-supplied data (forms, cookies, HTTP headers, etc.) to a system shell. They are made possible because of improper input validation, which in turn allows a bad actor to pass system commands via the web application.

 

Successful exploits can lead to:

loss of condidentiality;

Loss of integrity;

Loss of availability;

Loss of accountability;

The NOC WAF is able to mitigate attacks that try to abuse RCE vulnerabilities.

Protecting Against RCE Injection Vulnerabilities

Cloud-Based Protection

RCE vulnerabilities get exploited on web applications when bad actors are able pass malformed queries to the web server and the inputs are not properly validated.

 

NOC helps mitigate attacks that try to exploit these vulnerabilities through its virtual hardening and patching technology. As a reverse proxy, NOC sits between your web application, and the internet. When a user queries your web application, our network will inspect the query structure and ensure that it is not attempting to exploit a weakness.

 

One of the key features of the WAF platform is its ability to Virtually Harden and Patch web applications at the edge. This technology protects the application by preventing the attacker from hitting the application back-end.  The attack registers on our network, we detect, strip it from the request, and block the attacker from attempting further exploits against your application.

Secure Coding Best Practice

Flaws in code are bound to happen, but there are things all software developers can do to help reduce the risk of introducing a RCE vulnerability into their application.

Use of Prepared Statement (with Parameterized Queries)

Option 2: Use of Stored Procedures

Option 3: Allow-list Input Validation

Option 4: Escaping all User Supplied Input

Option 5: Enforcing Least Privilege
