The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4160 advisory.

  - 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)

  - In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP     address string. This (in some situations) allows attackers to bypass access control that is based on IP     addresses. (CVE-2021-29921)

  - An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in     the authority component, the authority regular expression exhibits catastrophic backtracking, causing a     denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect.
    (CVE-2021-33503)

  - There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince     another local or adjacent user to start a pydoc server could access the server and use it to disclose     sensitive information belonging to the other user that they would not normally be able to access. The     highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9,     Python versions before 3.9.3 and Python versions before 3.10.0a7. (CVE-2021-3426)

  - A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote     attacker could possibly use this issue to install a different revision on a repository. The highest threat     from this vulnerability is to data integrity. This is fixed in python-pip version 21.1. (CVE-2021-3572)

  - 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)

  - 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)
