CVE-2018-11758: Apache Cayenne XXE Vulnerability in CayenneModeler GUI tool Severity: Low Vendor: The Apache Software Foundation Versions Affected: Cayenne 4.1.M1 Cayenne 3.2.M1, 4.0.M2 to 4.0.M5, 4.0.B1, 4.0.B2, 4.0.RC1 Cayenne 3.1, 3.1.1, 3.1.2 The unsupported Cayenne 2.0.x, 3.0.x versions may be also affected Description: CayenneModeler is a desktop GUI tool for working with Cayenne ORM models stored as XML files. If an attacker tricks a user of CayenneModeler into opening a malicious XML file, the attacker will be able to instruct the XML parser built into CayenneModeler to transfer files from a local machine to a remote machine controlled by the attacker. The cause of the issue is XML parser processing XML External Entity (XXE) declarations included in XML. The vulnerability is addressed in Cayenne by disabling XXE processing in all operations that require XML parsing. Mitigation: 4.1.x users should upgrade to 4.1.M2 or newer. 4.0.x users should upgrade to 4.0 (GA release). 3.1.x users should upgrade to 3.1.3.
