Description
A flaw has been found in thinkgem JeeSite up to 5.15.1. Impacted is an unknown function of the file /com/jeesite/common/shiro/cas/CasOutHandler.java of the component Endpoint. Executing a manipulation can lead to xml external entity reference. The attack may be performed from remote. Attacks of this nature are highly complex. The exploitability is considered difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A XML External Entity (XXE) vulnerability has been identified in thinkgem JeeSite versions through 5.15.1. The issue resides in the Endpoint component, specifically within the file CasOutHandler.java. The vulnerability allows for the manipulation of XML data through a user-controlled POST parameter named logoutRequest. This parameter is processed as XML without adequate protections against XXE attacks, enabling an attacker to craft XML that could, for example, initiate server-side requests to external entities.
