There is a possible XSS vulnerability in all rails-html-sanitizer gem versions below 1.0.4 for Ruby. The gem allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments, and these attributes can lead to an XSS attack on target applications. This issue is similar to CVE-2018-8048 in Loofah. All users running an affected release should either upgrade or use one of the workarounds immediately.

An issue was discovered in zzcms 8.2. user/manage.php allows remote attackers to delete arbitrary files via directory traversal sequences in the oldimg or oldflv parameter in an action=modify request. This can be leveraged for database access by deleting install.lock.

An issue was discovered in zzcms 8.2. user/licence_save.php allows remote attackers to delete arbitrary files via directory traversal sequences in the oldimg parameter in an action=modify request. This can be leveraged for database access by deleting install.lock.

An issue was discovered in zzcms 8.2. It allows SQL injection via the id parameter in an adv2.php?action=modify request.

An issue was discovered in zzcms 8.2. It allows PHP code injection via the siteurl parameter to install/index.php, as demonstrated by injecting a phpinfo() call into /inc/config.php.

An issue was discovered in zzcms 8.2. user/ppsave.php allows remote attackers to delete arbitrary files via directory traversal sequences in the oldimg parameter in an action=modify request. This can be leveraged for database access by deleting install.lock.

An exploitable cross site scripting (XSS) vulnerability exists in the filter functionality of the delayed_job_web rails gem version 1.4. A specially crafted URL can cause an XSS flaw resulting in an attacker being able to execute arbitrary javascript on the victim's browser. An attacker can phish an authenticated user to trigger this vulnerability.

An exploitable cross site scripting (XSS) vulnerability exists in the add filter functionality of the rails_admin rails gem version 1.2.0. A specially crafted URL can cause an XSS flaw resulting in an attacker being able to execute arbitrary javascript on the victim's browser. An attacker can phish an authenticated user to trigger this vulnerability.

** DISPUTED ** SQL injection vulnerability in the 'find_by' method in Ruby on Rails 5.1.4 and earlier allows remote attackers to execute arbitrary SQL commands via the 'name' parameter. NOTE: The vendor disputes this issue because the documentation states that this method is not intended for use with untrusted input.

In the yajl-ruby gem 1.3.0 for Ruby, when a crafted JSON file is supplied to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in the yajl_string_decode function in yajl_encode.c. This results in the whole ruby process terminating and potentially a denial of service.
