Описание
REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or later include the patch to fix the vulnerability.
A flaw was found in the REXML XML toolkit for Ruby. Parsing XML data containing a large number of digits between &# and x...; in a hex numeric character reference (&#x...;) can trigger a regular expression denial of service (ReDoS) condition, leading to a denial of service.
Отчет
This vulnerability is rated as a moderate severity because it allows attackers to exploit inefficient regex parsing in hex numeric character references (&#x...;), causing a ReDoS and impacting availability, it requires specific malicious input but does not affect confidentiality or integrity.
