The web server access log shows a GET request from 104.210.233.225 to the path
"/../../../../conf/server.xml", which indicates a directory traversal attack. This type of attack allows an attacker to access sensitive files outside the intended directory structure, in this case, the server.xml configuration file, which may contain sensitive information such as credentials or system configurations.
The web application firewall (WAF) log does not show any specific blocking actions, suggesting that the attack was successful in retrieving and potentially exfiltrating sensitive data from the corporate web server.
