Worst Case
Malicious application gains full system access, modifies critical system files, installs persistent malware, or steals sensitive data from protected locations.
Likely Case
Malware or compromised legitimate applications modify user files, install unwanted software, or bypass security controls to establish persistence.
If Mitigated
With proper application sandboxing and security controls, impact is limited to specific applications rather than system-wide compromise.
🎯 Exploit Status
Exploitation requires a malicious or compromised application to be installed and executed on the target system. No remote exploitation vector identified.
