This tweet by @vgrichina and others indicates the release of a WAF bypass cheatsheet, described as a hacker's toolkit. Although the exact WAF vendor and bypass payload details are not specified in the tweet itself, the linked cheatsheet likely contains various techniques to bypass Web Application Firewalls (WAFs). Since WAFs are used to protect web applications from attacks like Cross-Site Scripting (XSS), SQL Injection (SQLi), and Remote Code Execution (RCE), this cheatsheet could cover multiple types of vulnerabilities and how to circumvent protections.
The nature of the tweet suggests a universal or broad approach, targeting multiple WAFs and vulnerabilities rather than a single specific product or bug. For anyone interested in web security, understanding such bypass methods is crucial to enhance WAF rules and strengthen website defenses. However, it is important to use this knowledge responsibly and ethically, focusing on improving security rather than exploiting it.
