CVE-2018-11788: Apache Karaf

Critical severity, CVSS 9.8. EPSS: 7.3% chance of exploitation in the next 30 days.

Apache Karaf provides a features deployer, which allows users to "hot deploy" a features XML by dropping the file directly in the deploy folder. The features XML is parsed by XMLInputFactory class. Apache Karaf XMLInputFactory class doesn't contain any mitigation codes against XXE. This is a potential security risk as an user can inject external XML entities in Apache Karaf version prior to 4.1.7 or 4.2.2. It has been fixed in Apache Karaf 4.1.7 and 4.2.2 releases.

Affected products

• Apache Karaf: before 4.1.7 (fixed in 4.1.7); from 4.2.0, up to and including 4.2.1; version 4.2.0 only
