MITRE ATT&CK Enterprise TechniquesAI

T1027.017 SVG Smuggling Stealth
Adversaries may smuggle data and files past content filters by hiding malicious payloads inside of seemingly benign SVG files.
T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
Why these techniques?

Stored XSS via unsanitized SVG markdown enables SVG smuggling for obfuscation (T1027.017), JavaScript code execution in admin browser (T1059.007), exploitation of public-facing web application (T1190), and credential theft via session cookie stealing (T1539).
