Severity: Important
Vendor:
The Apache Software Foundation
Versions Affected:
Roller 5.2.1
Roller 5.2
The unsupported pre-Roller 5.1 versions may also be affected.
Description:
Roller relies on Java SAX Parser to implement its XML-RPC interface and by
default that parser supports external entities in XML DOCTYPE, which opens
Roller up to SSRF / File Enumeration vulnerability. Note that this
vulnerability exists even if Roller XML-RPC interface is disable via the
Roller web admin UI.
Mitigation:
There are a couple of ways you can fix this vulnerability:
1) Upgrade to the latest version of Roller, which is now 5.2.2
2) Or, edit the Roller web.xml file and comment out the XML-RPC Servlet
mapping as shown below:
<!--
<servlet-mapping>
<servlet-name>XmlRpcServlet</servlet-name>
<url-pattern>/roller-services/xmlrpc</url-pattern>
</servlet-mapping>
-->
