📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain administrative control over the Aspera Orchestrator instance, potentially accessing sensitive data, modifying configurations, or disrupting data transfer operations.
Likely Case
Attackers could perform unauthorized actions within the user's privilege level, such as modifying transfer settings, accessing data, or changing configurations.
If Mitigated
With proper CSRF protections and user awareness, the risk is significantly reduced as exploitation requires user interaction with malicious content.
