Why these techniques?

Path traversal in package folder editing allows authenticated users to download and place malicious scripts in pyLoad's execution directories (e.g., /config/scripts/package_deleted/), enabling RCE. Facilitates exploitation of public-facing web applications (T1190), remote services (T1210), and privilege escalation (T1068).
