CVE-2025-20329 — Cisco TelePresence Collaboration Endpoint and RoomOS Software Information Disclosure Vulnerability

A vulnerability in the logging component of Cisco TelePresence Collaboration Endpoint (CE) and Cisco RoomOS Software could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability exists because certain unencrypted credentials are stored when SIP media component logging is enabled. An attacker could exploit this vulnerability by accessing the audit logs on an affected system and obtaining credentials to which they may not normally have access. A successful exploit could allow the attacker to use those credentials to access confidential information, some of which may contain personally identifiable information (PII). Note: To access the logs that are stored in the Webex Cloud or stored on the device itself, an attacker must have valid administrative credentials.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.4% (30-day exploitation probability)+4
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Cisco Cisco RoomOS Software, Cisco Roomos, Cisco Telepresence Collaboration Endpoint).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
