CVE-2025-20329
📋 TL;DR
This vulnerability allows authenticated administrators on Cisco TelePresence and RoomOS systems to view unencrypted credentials in audit logs when SIP media logging is enabled. Attackers with administrative access can obtain credentials they shouldn't have, potentially accessing sensitive information including PII. Only systems with SIP media component logging enabled are affected.
💻 Affected Systems
- Cisco TelePresence Collaboration Endpoint (CE)
- Cisco RoomOS Software
📦 What is this software?

⚠️ Risk & Real-World Impact
Worst Case
Administrator obtains credentials for other systems/services, accesses confidential data including PII, and potentially moves laterally within the network.
Likely Case
Administrator discovers and misuses credentials for adjacent systems, leading to unauthorized access to sensitive information.
If Mitigated
With proper access controls and monitoring, credential misuse is detected and contained before significant damage occurs.
🎯 Exploit Status
Requires administrative credentials and access to logs (either locally or in Webex Cloud).
