Web Vulnerability

Web vulnerabilities usually refer to vulnerabilities in website programs, which may be caused by code writers' inadequate consideration when writing code. Common web vulnerabilities include SQL injection, CSRF, XSS vulnerabilities, upload vulnerabilities, and arbitrary file reading, command execution, file inclusion, etc.

0day Vulnerability

0day vulnerabilities generally refer to security vulnerabilities that are maliciously exploited immediately after being discovered or disclosed. Due to the time lag between the disclosure of these vulnerabilities and the release of official website vulnerability patches, attacks are often very sudden and disruptive.
