high Nessus Plugin ID 298242

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco TelePresence Collaboration Endpoint Software and RoomOS Software Denial of Service is affected by a vulnerability.

 - A vulnerability in the text rendering subsystem of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of input received by an affected device. An attacker could exploit this vulnerability by getting the affected device to render crafted text, for example, a crafted meeting invitation. As indicated in the CVSS score, no user interaction is required, such as accepting the meeting invitation. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. (CVE-2026-20119)
