要点

CVE-2017-18635 は novnc (novnc), openstack (redhat), @novnc/novnc に影響する深刻度「中」 (CVSS 6.1) の脆弱性です。
今後30日間に悪用される確率（EPSS）：4.8%（全脆弱性の 91.9% より高い）。
対処：0.6.2 以降に更新してください。

パッケージ	影響を受けるバージョン	修正済みバージョン
novnc novnc	`< 0.6.2`	`0.6.2`
openstack redhat	`= 13`	修正版なし
@novnc/novnc npm	`< 0.6.2`	`0.6.2`

概要

Versions of @novnc/novnc prior to 0.6.2 are vulnerable to Cross-Site Scripting (XSS). The package fails to validate input from the remote VNC server such as the VNC server name. This allows an attacker in control of the remote server to execute arbitrary JavaScript in the noVNC web page. It affects any users of include/ui.js and users of vnc_auto.html and vnc.html.

Recommendation

Upgrade to version 0.6.2 or later.

NVD の説明

An XSS vulnerability was discovered in noVNC before 0.6.2 in which the remote VNC server could inject arbitrary HTML into the noVNC web page via the messages propagated to the status field, such as the VNC server name.
