RCE

Jan 1, 0001

Definition

Remote Code Execution (RCE) is a critical security vulnerability that allows an attacker to execute arbitrary code on a target system remotely. This type of vulnerability can arise from improper validation of user inputs, insecure deserialization, or flaws in software logic, enabling attackers to gain control over the affected system. RCE can lead to severe consequences, including data breaches, unauthorized access, and system compromise.

Secure Settings Example

# Example of a secure configuration in a web application firewall (WAF)
rules:
  - id: 1001
    action: block
    conditions:
      - match: request.uri
        pattern: ".*(\\.|\\(|\\)|\\{|\\}|\\[|\\]|\\;|\\$|\\`).*"
        negate: false
    description: "Block requests with suspicious characters to prevent RCE"

Insecure Settings Example

# Example of an insecure configuration in a web application
allow_user_input_execution: true
# This setting allows user input to be executed as code, leading to potential RCE vulnerabilities.
