Synopsis

Description

According to the version of the python-lxml package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - An issue was discovered in lxml before 4.2.5.
 lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by 'j a v a s c r i p t:' in Internet Explorer. This is a similar issue to CVE-2014-3146.(CVE-2018-19787)
