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. Satellite employs multiple versions of ReXML in the Puppet Agent and Server components across varying versions of Satellite:
- In Satellite 6.15 (on RHEL8), the Puppet Agent component uses ReXML version 7.28-0-1 and IS affected.
- In Satellite 6.15 (on RHEL8), the Satellite server component uses ReXML version 7.17.2-1 and is NOT affected.
- In Satellite 6.16 and 6.17 (on RHEL8 and RHEL9), the Puppet Agent component uses ReXML version 8.8.1-1 and is NOT affected.
- In Satellite 6.16 and 6.17 (on RHEL8 and RHEL9), the Satellite server component uses ReXML version 8.6.2-2 and IS affected. To reiterate, only the Puppet Agent component in Satellite 6.15 and the Satellite server component in Satellite 6.16 and 6.17 are affected. Any other component/Satellite version combinations are considered not-affected.
