CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2019-17022 – Mozilla: CSS sanitization does not escape HTML tags
https://notcve.org/view.php?id=CVE-2019-17022
When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. Al pegar un <style> etiqueta del portapapeles en un editor de texto enriquecido, el saneador CSS no escapa caracteres < y >. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00043.html http://packetstormsecurity.com/files/155912/Slackware-Security-Advisory-mozilla-thunderbird-Updates.html https://access.redhat.com/errata/RHSA-2020:0085 https://access.redhat.com/errata/RHSA-2020:0086 https://access.redhat.com/errata/RHSA-2020:0111 https://access.redhat.com/errata/RHSA-2020:0120 https://access.redhat.com/errata/RHSA-2020:0123 https: • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
