Improper Restriction of XML External Entity Reference
A flaw was found in codehaus-plexus versions prior to 3.0.24. The 'org.codehaus.plexus.util.xml.XmlWriterUtil#writeComment' fails to sanitize comments for a ' -->' sequence. This issue means that text contained in the command string could be interpreted as XML and allow for XML injection.
CWE-611 - Improper Restriction of XML External Entity Reference
Listed 4th in the 'OWASP Top Ten', XML External Entities (XXE) vulnerability allows attackers to provide an XML input that contains an external entity. When the XML is parsed, it can cause data extraction and manipulation, execution of commands, denial-of-service attacks, and server-side request forgery.
