CVE-2016-4047: n/a vulnerability

CVE-2016-4047: An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev8.

An issue was discovered in Open-Xchange OX App Suite before 7.8.1-rev8. References to external Open XML document type definitions (.dtd resources) can be placed within .docx and .xslx files. Those resources were requested when parsing certain parts of the generated document. As a result an attacker can track access to a manipulated document. Usage of a document may get tracked and information about internal infrastructure may get exposed.

Security readout for executives and security teams

CVE-2016-4047 is a privacy and information-disclosure issue in Open-Xchange OX App Suite before 7.8.1-rev8. A manipulated Office document could cause the application to request attacker-controlled external DTD resources during parsing, letting the attacker track document access and potentially learn internal infrastructure details. Exposure is likely limited to organizations running Open-Xchange OX App Suite versions earlier than 7.8.1-rev8 that process manipulated .docx or .xlsx files through the affected document handling path. Treat this as a moderate-priority privacy and exposure issue. It is not described as remote code execution, but it can reveal internal network details and document access patterns if affected systems handle malicious Office files. Mitigation focus: Upgrade Open-Xchange OX App Suite to 7.8.1-rev8 or a later supported release.; Review the Open-Xchange advisory for exact package and deployment guidance.; Limit processing of untrusted .docx and .xlsx files until affected instances are updated..
