CVE-2023-20094

Adjacent information disclosure via out-of-bounds read

Published Nov 15, 2024 · Updated Nov 15, 2024

Out-of-bounds read in Cisco TelePresence CE and RoomOS allows remote attackers to disclose sensitive data from Webex Desk Hub. Cisco has not identified the request handler or protocol; it states only that improper bounds checks on a crafted request cause the out-of-bounds read. Exploitation requires unauthenticated access from an adjacent network and exposes device memory without reported write or availability impact.
