Why these techniques?

The reflected/stored XSS vulnerability in the public-facing /register.php endpoint enables exploitation of public-facing web applications (T1190) and facilitates JavaScript execution in victims' browsers (T1059.007), as explicitly mapped in the VulDB advisory. This allows arbitrary script injection for potential credential theft or other attacks.
