CVE-2025-20329

4.9 MEDIUM

📋 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

Products:
  • Cisco TelePresence Collaboration Endpoint (CE)
  • Cisco RoomOS Software
Versions: All versions before the fix
Operating Systems: Cisco RoomOS
Default Config Vulnerable: ✅ No
Notes: Only vulnerable when SIP media component logging is enabled. Requires administrative credentials to exploit.

📦 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.

🌐 Internet-Facing: LOW
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires administrative credentials and access to logs (either locally or in Webex Cloud).
