According to the versions of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • This flaw allows a malicious HTTP server to set ‘super cookies’ in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl’s function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with domain=co.UK when the URL used a lower case hostname curl.co.uk, even though co.uk is listed as a PSL domain. (CVE-2023-46218)

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.
