Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload Vulnerability

🚨 An authenticated admin can upload a ZIP file that opens the door to arbitrary file access—like handing a key to a mischievous magician! 🔥 Think of it as a delivery driver who doesn’t double-check what’s inside their packages. If they’re not careful, they might drop off sensitive files instead of the intended gifts! This vulnerability allows an attacker with admin rights to perform directory traversal, potentially accessing files that should remain secure. The consequences could be absolutely devastating—sensitive data leaks and unauthorized system changes could be just the start!
