Vulnerability from github – Published: 2022-04-28 19:31 – Updated: 2022-04-28 19:31
VLAI
Summary
Arbitrary file access through XML parsing in org.xwiki.commons:xwiki-commons-xml
Details

Impact

It's possible in a script to access any file accessing to the user running XWiki application server with XML External Entity Injection through the XML script service.

For example:

{{velocity}}
#set($xml=$services.get('xml'))
#set($xxe_payload = "<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE root[<!ENTITY xxe SYSTEM 'file:///etc/passwd' >]><root><foo>&xxe;</foo></root>")
#set($doc=$xml.parse($xxe_payload))
$xml.serialize($doc)
{{/velocity}}

Patches

The problem has been patched on versions 12.10.10, 13.4.4 and 13.8RC1.

Workarounds

There's no easy workaround for fixing this vulnerability other than upgrading and being careful when giving Script rights.

Vulnerability from github – Published: 2022-05-24 19:17 – Updated: 2022-05-24 19:17
VLAI
Details

SAP BusinessObjects Business Intelligence Platform (Crystal Reports) - versions 420, 430, allows an unauthenticated attacker to exploit missing XML validations at endpoints to read sensitive data. These endpoints are normally exposed over the network and successful exploitation can enable the attacker to retrieve arbitrary files from the server.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
