| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
XWiki Platform versions prior to 13.10.11
XWiki Platform versions prior to 14.4.7
XWiki Platform versions prior to 14.10-rc-1
Description
The XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions, any user with edit rights on a document can trigger an XAR import on a forged XAR file, leading to the ability to display the content of any file on the XWiki server host. This issue can be exploited by creating a forged XAR file with a
package.xml content that includes an ENTITY referencing a file on the server, such as file:///etc/passwd, and then uploading it to a wiki page and triggering the import using a specific URL, for example, http://localhost:8080/xwiki/bin/view/Main/XXE?sheet=XWiki.AdminImportSheet&file=test.xar.Recommendations
For versions prior to 13.10.11, upgrade to version 13.10.11 or later.
For versions prior to 14.4.7, upgrade to version 14.4.7 or later.
For versions prior to 14.10-rc-1, upgrade to version 14.10-rc-1 or later.
As a temporary workaround for users unable to upgrade, apply the patch
e3527b98fd manually to the XarPackage java class.Exploit
