The tweet discusses a real-world scenario of bypassing WAF filtering using SQL injection with a filter bypass via XML encoding. This method allows the attacker to evade WAF detection and potentially exploit SQL injection vulnerabilities in the application. The use of Hackvertor for bypassing the filtering is highlighted. This bypass technique can be significant in scenarios where WAF protection needs to be circumvented to carry out attacks. The tweet provides a brief overview, but a detailed blog post can be created with technical details on the bypass method, the WAF vendor, and the implications of the bypass in a practical scenario.
