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-2019-20139

Rule Vulnerability

Cross Site Scripting (XSS)

Cross Site Scripting (XSS) attackers send malicious input to a site that does not validate the input, usually in the form of a script. The application sends the malicious code to the browsers of other users, which will execute the script unknowingly. The malicious code uses the trust of the host website to access cookies, session tokens, or other sensitive information. There are multiple types of XSS, including Stored, Reflected, and DOM based.
