GLSA-202208-06

The remote host is affected by the vulnerability described in GLSA-202208-06 (lxml: Multiple Vulnerabilities)

  - An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling     the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute     allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS     code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.
    (CVE-2021-28957)

  - lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML     Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG     files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should     upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available. (CVE-2021-43818)

  - NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only     applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not     affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the     application. The vulnerability is caused by the iterwalk function (also used by the canonicalize     function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be     replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N     would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If     untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.
    (CVE-2022-2309)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-1821 advisory.

  - There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP     server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of     Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the     server to the client. The greatest threat that this flaw poses is to application availability.
    (CVE-2021-3733)

  - lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML     Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG     files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should     upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available. (CVE-2021-43818)

  - A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform     Resource Locator (URL) strings into components. The issue involves how the urlparse method does not     sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to     input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1,     3.9.5, 3.8.11, 3.7.11 and 3.6.14. (CVE-2022-0391)

  - python: ftplib should not use the host from the PASV response (CVE-2021-4189)

  - A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may     allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop,     consuming CPU time. The highest threat from this vulnerability is to system availability. (CVE-2021-3737)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two     content-length headers, it ignored the first header. When the second content-length value was set to zero,     the request body was interpreted as a pipelined request. (CVE-2020-10108)

  - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a     content-length and a chunked encoding header, the content-length took precedence and the remainder of the     request body was interpreted as a pipelined request. (CVE-2020-10109)

  - 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)

  - In PyYAML before 5.1, the yaml.load() API could execute arbitrary code if used with untrusted data. The     load() function has been deprecated in version 5.1 and the 'UnsafeLoader' has been introduced for backward     compatibility with the function. (CVE-2017-18342)

  - Django before 2.2.24, 3.x before 3.1.12, and 3.2.x before 3.2.4 has a potential directory traversal via     django.contrib.admindocs. Staff members could use the TemplateDetailView view to check the existence of     arbitrary files. Additionally, if (and only if) the default admindocs templates have been customized by     application developers to also show file contents, then not only the existence but also the file contents     would have been exposed. In other words, there is directory traversal outside of the template root     directories. (CVE-2021-33203)

  - In Django 2.2 before 2.2.24, 3.x before 3.1.12, and 3.2 before 3.2.4, URLValidator, validate_ipv4_address,     and validate_ipv46_address do not prohibit leading zero characters in octal literals. This may allow a     bypass of access control that is based on IP addresses. (validate_ipv4_address and validate_ipv46_address     are unaffected with Python 3.9.5+..) . (CVE-2021-33571)

  - In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with     trailing newlines could bypass upstream access control based on URL paths. (CVE-2021-44420)

  - In Django 2.2 before 2.2.21, 3.1 before 3.1.9, and 3.2 before 3.2.1, MultiPartParser, UploadedFile, and     FieldFile allowed directory traversal via uploaded files with suitably crafted file names.
    (CVE-2021-31542)

  - In Django 2.2 before 2.2.20, 3.0 before 3.0.14, and 3.1 before 3.1.8, MultiPartParser allowed directory     traversal via uploaded files with suitably crafted file names. Built-in upload handlers were not affected     by this vulnerability. (CVE-2021-28658)
