CVE-2023-45137
No affected components available
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. org.xwiki.platform:xwiki-platform-web starting in version 3.1-milestone-2 and prior to version 13.4-rc-1, as well as org.xwiki.platform:xwiki-platform-web-templates prior to versions 14.10.12 and 15.5-rc-1, are vulnerable to cross-site scripting. When trying to create a document that already exists, XWiki displays an error message in the form for creating it. Due to missing escaping, this error message is vulnerable to raw HTML injection and thus XSS. The injected code is the document reference of the existing document so this requires that the attacker first creates a non-empty document whose name contains the attack code. This has been patched in org.xwiki.platform:xwiki-platform-web version 13.4-rc-1 and org.xwiki.platform:xwiki-platform-web-templates versions 14.10.12 and 15.5-rc-1 by adding the appropriate escaping. The vulnerable template file createinline.vm is part of XWiki's WAR and can be patched by manually applying the changes from the fix.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
