This tweet describes a successful bypass of a Web Application Firewall (WAF) that led to Remote Code Execution (RCE) and obtaining a reverse shell. The user indicates that the process took several hours and involved using obfuscators and various evasion techniques. Although the exact payload and WAF vendor are not mentioned, the tweet highlights the challenges and persistence needed to bypass modern WAFs protecting against RCE vulnerabilities. Obfuscation and evasion are common strategies attackers use to circumvent WAF rules that filter suspicious or known malicious payloads. Getting RCE and reverse shell access signifies a dangerous breach, allowing an attacker to execute arbitrary commands and potentially take full control over the affected system. This example underscores the importance for organizations to continuously improve their WAFs and regularly update detection rules to defend against advanced evasion methods.
