⚡ Your Zimbra instance might just be the key to a treasure trove of internal data! An SSRF vulnerability lurking in ProxyServlet could let attackers peek behind the curtain. 🚨 Think of ProxyServlet as a trusted concierge in a hotel, who mistakenly believes every guest's request is valid and fetches information from locked-off areas of the hotel without verifying their identity. An attacker can exploit this vulnerability to access sensitive internal resources, potentially leaking data or launching further attacks. It’s like handing a stranger the keys to your secret vault because they had a convincing story — absolutely devastating!
