Official Description
Liferay Portal Community Edition (CE) 6.x before 6.0.6 GA, when Apache Tomcat is used, allows remote authenticated users to read arbitrary files via an entity declaration in conjunction with an entity reference, related to an XML External Entity (aka XXE) issue.
Technical Analysis
CVE-2011-1502 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
