RULE（RULE ID：339983）

Rule General Information
Release Date: 2026-05-06
Rule Name: Command Injection Detection - Bypass Attack
Severity:
CVE ID:
Rule Protection Details
Description: This rule detects Windows command injection attacks with various obfuscation techniques to bypass security controls. The attacks use obfuscation techniques such as quote insertion ("), caret escaping (^), and parenthesis wrapping to evade detection by WAF and security filters.
Impact: Successful exploitation allows an attacker to execute arbitrary Windows commands on the target server, leading to complete system compromise, data theft, and further lateral movement. Obfuscation techniques make detection more difficult for traditional security solutions.
Affected OS: Windows
Reference:
Solutions
Implement strict input validation and sanitization for all user inputs. Disable or restrict command execution functions in the application. Use a whitelist approach for allowed commands. Implement proper sandboxing for command execution. Monitor for suspicious command injection activities.
