MITRE::ATT&CK Framework::Enterprise::Initial Access::Exploit Public-Facing Application

Adversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other applications with Internet accessible open sockets, such as web servers and related services.

CVE

CVE-2024-33615

Rule Vulnerability

Directory Traversal

A Directory Traversal attack targets HTTP traffic and allows the attacker to access directories outside the applications own, potentially exposing sensitive system files to leakage or overwriting. This is also known as Directory Climbing, Path Traversal, or Backtracking. An alert on this kind of attack indicates a vulnerability in security validation of user input that allows a "traverse to parent directory" or "../" command to pass through. Protect your site by filtering all user input, removing any characters but the allowed data.
