Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3714-1 advisory.

- rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Certain configurations of rails-html-sanitizer < 1.4.4 use an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. This issue has been patched in version 1.4.4. (CVE-2022-23517)

- rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Versions >= 1.0.3, < 1.4.4 are vulnerable to cross-site scripting via data URIs when used in combination with Loofah >= 2.1.0. This issue is patched in version 1.4.4. (CVE-2022-23518)

- rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags in either of the following ways: allow both math and style elements, or allow both svg and style elements. Code is only impacted if allowed tags are being overridden. . This issue is fixed in version 1.4.4. All users overriding the allowed tags to include math or svg and style should either upgrade or use the following workaround immediately: Remove style from the overridden allowed tags, or remove math and svg from the overridden allowed tags. (CVE-2022-23519)

- rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, there is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer due to an incomplete fix of CVE-2022-32209. Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both select and style elements. Code is only impacted if allowed tags are being overridden. This issue is patched in version 1.4.4. All users overriding the allowed tags to include both select and style should either upgrade or use this workaround: Remove either select or style from the overridden allowed tags. NOTE: Code is
_not_ impacted if allowed tags are overridden using either the :tags option to the Action View helper method sanitize or the :tags option to the instance method SafeListSanitizer#sanitize. (CVE-2022-23520)

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

Solution

Update the affected ruby2.5-rubygem-rails-html-sanitizer, ruby2.5-rubygem-rails-html-sanitizer-doc and / or ruby2.5-rubygem-rails-html-sanitizer-testsuite packages.
