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

  - A XSS vulnerability was discovered in python-lxml's     clean module. The module's parser didn't properly     imitate browsers, which caused different behaviors     between the sanitizer and the user's page. A remote     attacker could exploit this flaw to run arbitrary     HTML/JS code.(CVE-2020-27783)

  - 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)

  - Incomplete blacklist vulnerability in the     lxml.html.clean module in lxml before 3.3.5 allows     remote attackers to conduct cross-site scripting (XSS)     attacks via control characters in the link scheme to     the clean_html function.(CVE-2014-3146)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

python-lxml was fixed to ensure proper input sanitization in clean_html (CVE-2014-3146).

Updated python-lxml packages fix security vulnerability :

The clean_html() function, provided by the lxml.html.clean module, did not properly clean HTML input if it included non-printed characters (\x01-\x08). A remote attacker could use this flaw to serve malicious content to an application using the clean_html() function to process HTML, possibly allowing the attacker to inject malicious code into a website generated by this application (CVE-2014-3146).

This security update for python-lxml fixes a input sanitization flaw in clean_html. (CVE-2014-3146)

It was discovered that the lxml.html.clean module incorrectly stripped control characters. An attacked could potentially exploit this to conduct cross-site scripting (XSS) attacks.

It was discovered that clean_html() function of lxml (pythonic bindings for the libxml2 and libxslt libraries) performed insufficient sanitisation for some non-printable characters. This could lead to cross-site scripting.
