According to the versions of the python-urllib3 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
POST
) to GET
as is required by HTTP RFCs.redirects=False
and disable automatic redirects with redirects=False
and handle 301, 302, and 303 redirects manually by stripping the HTTP request body. (CVE-2023-45803)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.

"According to the versions of the python-urllib3 package installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :
- urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP
request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method
changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs.
Although this behavior is not specified in the section for redirects, it can be inferred by piecing
together information from different sections and we have observed the behavior in other major HTTP client
implementations like curl and web browsers. Because the vulnerability requires a previously trusted
service to become compromised in order to have an impact on confidentiality we believe the exploitability
of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request
bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions
must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information
in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts
redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised.
This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve
this issue. Users unable to update should disable redirects for services that aren't expecting to respond
with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle
301, 302, and 303 redirects manually by stripping the HTTP request body. (CVE-2023-45803)
