Question 43/56
A security team needs to prevent a remote code execution vulnerability. The vulnerability can be exploited only by sending '${ string in the HTTP request. WAF rule is blocking '${', but system engineers detect that attackers are executing commands on the host anyway. Which action should the security team recommend?
Correct Answer: A
When Web Application Firewalls (WAFs) are configured to block specific patterns (like${), attackers may bypass this using URL encoding (e.g.,%24%7B). In such cases, the WAF must decode these patterns before applying matching rules. EnablingURL decodingensures the WAF recognizes encoded payloads and applies protections appropriately. This is a recommended hardening strategy against bypass techniques for command injection and remote code execution.
