An XML injection issue, also known as blind XPath injection, exists in the Mediawiki - EasyTimeline extension. This allows an attacker to inject XML, which can be used to manipulate XPath queries to extract information from the XML document structure without the application returning the results directly in the response.

The issue is related to Improper Neutralization of Input During Web Page Generation, also known as Cross-site Scripting. This affects Apache Archiva, a product that is no longer supported by its maintainer. As a result, no fix is planned for this issue. Users are advised to find an alternative or restrict access to the instance to trusted users. An additional mitigation measure is to configure an HTTP proxy in front of the Archiva instance to filter out requests with malicious characters in the URL.
