How the Exploit Works
The vulnerability works by exploiting the way the XWiki Platform handles requests through jsx and sx endpoints. By crafting specific URLs, an attacker can bypass security restrictions and gain access to configuration files that are typically restricted. These files can contain sensitive information that could be used for further exploitation of the system.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. This HTTP request could potentially access a configuration file:
GET /bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false HTTP/1.1
Host: localhost:8080Mitigation
Users of affected XWiki versions are advised to upgrade to version 16.10.7 or later. If an immediate upgrade is not possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure. Regular monitoring for any suspicious activity is also recommended until a permanent solution is implemented.
