Cisco Roomos Software
Monthly
Root-level code execution in Cisco RoomOS via the USB driver allows an unauthenticated attacker with physical access to a device's USB port to achieve full system compromise by connecting a malicious USB device. The vulnerability spans a wide range of RoomOS versions across the 10.x, 11.x, and 26.x release families, covering the Cisco Webex Room and Board series of video collaboration endpoints. No public exploit code has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, but the root-level impact (C:H/I:H) and the unattended nature of conference room hardware make this a meaningful physical security risk.
Credential exposure in Cisco RoomOS allows an authenticated low-privilege local user to capture user login credentials by enabling a specific debug logging level and collecting the resulting system logs. The flaw (CWE-532) spans a wide version range from RoomOS 10.x through 26.x across Cisco's entire room collaboration device portfolio. No public exploit code has been identified and this CVE does not appear in the CISA KEV catalog at time of analysis, but the High confidentiality impact - plaintext credential disclosure - warrants prioritized patching on any device with non-administrative local accounts.
Denial of service in Cisco RoomOS software allows remote unauthenticated attackers to exhaust availability of affected collaboration endpoints and room-based video devices through improper handling of exceptional conditions (CWE-703). The issue was internally discovered by Cisco's RoomOS engineering team as part of a hardening release bundling multiple flaws under this identifier, carries a CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), and has no public exploit identified at time of analysis. Note that the CVSS vector reflects availability-only impact even though a source tag labels it 'Information Disclosure,' a discrepancy defenders should verify against the Cisco advisory.
Remote denial of service in Cisco RoomOS software allows unauthenticated attackers to exhaust or corrupt a resource over the network, disrupting availability of Cisco collaboration room endpoints. Disclosed as part of a Cisco-internal security hardening review under the CWE-664 resource-lifetime pillar, the flaw carries a 7.5 CVSS score with an availability-only impact (C:N/I:N/A:H). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in Cisco RoomOS software allows remote, unauthenticated attackers to disrupt device availability through improperly validated input, resulting in a high availability impact (CVSS 7.5). The flaw was internally discovered during a Cisco engineering security review and shipped in a software hardening release bundling multiple CWE-20 input-validation issues. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Missing-encryption weaknesses in Cisco RoomOS software (the OS for Cisco Webex/Room collaboration endpoints) were fixed in an internal-hardening release covering multiple internally discovered issues grouped under CWE-311. Because sensitive data or communications are not adequately encrypted, network-positioned attackers could intercept or expose information handled by affected devices. There is no public exploit identified at time of analysis and this CVE is not in CISA KEV; EPSS is negligible at 0.06% (0th percentile), consistent with SSVC 'Exploitation: none.' Note the published CVSS 9.8 (C:H/I:H/A:H) sits uneasily against a CWE-311/Information-Disclosure classification, which normally implies a confidentiality-centric impact.
Memory-corruption vulnerabilities in Cisco RoomOS Software, disclosed by Cisco as a bundled hardening release from an internal security review, are scored CVSS 9.8 and could let remote unauthenticated attackers trigger buffer-overflow conditions on Cisco video collaboration endpoints. Per the CVSS vector the flaw is network-reachable with no authentication or user interaction and yields total impact to confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, EPSS is low (0.23%), and CISA SSVC records exploitation status as none, indicating no observed exploitation despite the critical score.
Privilege escalation via improper access control in Cisco RoomOS software allows an authenticated attacker with low-level privileges to gain full control over affected collaboration endpoints, with high impact to confidentiality, integrity, and availability. The issue was discovered internally by Cisco's RoomOS engineering team during a proactive security review and is one of several access-control weaknesses grouped under CVE-2026-20150 and resolved in a single hardening release. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.
