What the vulnerability does

01Description

Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a weblog administrator to read files readable by the Roller process and reach internal network addresses by importing a crafted OPML document, because the bookmark import parser does not disable external entity resolution. No non-default configuration is required; the import is reached through the administrator bookmark-import action. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which uses a hardened parser that disables external entities and document type declarations.
