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

    URI is a module providing classes to handle Uniform Resource Identifiers. In versions prior to 0.12.5,
    0.13.3, and 1.0.4, a bypass exists for the fix to CVE-2025-27221 that can expose user credentials. When
    using the `+` operator to combine URIs, sensitive information like passwords from the original URI can be
    leaked, violating RFC3986 and making applications vulnerable to credential exposure. Versions 0.12.5,
    0.13.3, and 1.0.4 fix the issue.(CVE-2025-61594)

    REXML is an XML toolkit for Ruby. The REXML gems from 3.3.3 to 3.4.1 has a DoS vulnerability when parsing
    XML containing multiple XML declarations. If you need to parse untrusted XMLs, you may be impacted to
    these vulnerabilities. The REXML gem 3.4.2 or later include the patches to fix these
    vulnerabilities.(CVE-2025-58767)

Tenable has extracted the preceding description block directly from the EulerOS ruby security advisory.

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